Are We Irrational?
Have you ever had someone in the culture tell you that ‘people of faith’ are simple minded folks who blindly believe that God exists in spite of overwhelming evidence to the contrary? Secularists often portray Christians as both ‘unreasonable’ and ‘unreasoning’. They simply believe that we have no idea what the evidence demonstrates related to the existence of God. They think we have blind faith, and they think we are comfortable with our blind obedience to the traditions of religion. Well I, for one, have never seen my faith in this way. I was an atheist for thirty five years because I believed that there was sufficient evidence to support naturalism. I will confess to you that I also thought that naturalism was the more reasonable worldview and that naturalists in general were more thoughtful and evidential. I thought that secularists and philosophical naturalists (I was both) were more committed to a rational examination of the evidence.

I found plenty of skepticism amongst naturalists and other historic thinkers who have questioned the reasoning ability of believers. Many well respected writers have challenged the rationality of ‘blind faith’ and (along with it) Christian Theism:

Thomas Jefferson
“Question with boldness even the existence of a God; because, if there be one, he must more approve of the homage of reason, than that of blind-folded fear”

Anais Nin
“When we blindly adopt a religion, a political system, a literary dogma, we become automatons. We cease to grow.”

Francis Bacon
“Atheism leaves a man to sense, to philosophy, to natural piety, to laws, to reputation; all of which may be guides to an outward moral virtue, even if religion vanished; but religious superstition dismounts all these and erects an absolute monarchy in the minds of men.”

Sir Julian Huxley
“Today the god hypothesis has ceased to be scientifically tenable … and its abandonment often brings a deep sense of relief. Many people assert that this abandonment of the god hypothesis means the abandonment of all religion and all moral sanctions. This is simply not true. But it does mean, once our relief at jettisoning an outdated piece of ideological furniture is over, that we must construct some thing to take its place”

But is this criticism valid? Are these observations true? Are those who believe in the existence of God truly holding on to an “outdated piece of ideological furniture”? Is it possible to be ‘reasonable’ and a theist at the same time? Is faith truly ‘blind’ or is it the result of a rational examination of the evidence? One thing is for sure, the concept of ‘blind faith’ is completely foreign to the Christian Worldview.

A Rational God
The God of the Bible does not call his children to obey blindly. The Bible itself serves as a piece of evidence, the testimony of eyewitnesses who are providing us with reasons to believe. That’s why the scriptures repeatedly call us to have a reasoned belief in Christ, and not to resort to the behavior of unreasoning animals:

Jude 4, 10
For certain persons have crept in unnoticed, those who were long beforehand marked out for this condemnation, ungodly persons who turn the grace of our God into licentiousness and deny our only Master and Lord, Jesus Christ…But these men revile the things which they do not understand; and the things which they know by instinct, like unreasoning animals, by these things they are destroyed.

The Bible uses this word for ‘unreasoning’ in a pejorative manner; to be unreasoning is to act like an animal. God clearly wants us to use our heads! In fact, God wants us to examine all the evidence that is at our disposal and to study the things of God with great intensity. When we do this, we truly begin to worship Him with our mind:

Matthew 22:37-38
“You shall love the Lord your God with all your heart, and with all your soul, and with all your mind. This is the great and foremost commandment.”

Believe it or not, our God is in the business of providing us with evidence. He wants us to be convinced after we examine the proof. Look at how Jesus dealt with the disciples following His resurrection:

Acts 1:2-3
…until the day when He was taken up, after He had by the Holy Spirit given orders to the apostles whom He had chosen. To these He also presented Himself alive, after His suffering, by many convincing proofs, appearing to them over a period of forty days, and speaking of the things concerning the kingdom of God.

Paul apparently took this high view of evidence very seriously. Just listen to this portion of Paul’s message to the Athenians:

Acts 17:30-31
“Therefore having overlooked the times of ignorance, God is now declaring to men that all everywhere should repent, because He has fixed a day in which He will judge the world in righteousness through a Man whom He has appointed, having furnished proof to all men by raising Him from the dead.”

The earliest of Christians understood the connection between reason, logic and faith, and they did not see these concepts as mutually exclusive. In fact, Paul often used reason to make his case for Christianity and he valued those who would also use reason to investigate the evidence that he offered:

Acts 17:2-3
And according to Paul’s custom, he went to them, and for three Sabbaths reasoned with them from the Scriptures, explaining and giving evidence that the Christ had to suffer and rise again from the dead

Acts 17:10-11
And the brethren immediately sent Paul and Silas away by night to Berea; and when they arrived, they went into the synagogue of the Jews. Now these were more noble-minded than those in Thessalonica, for they received the word with great eagerness, examining the Scriptures daily, to see whether these things were so.

As Christians, we are encouraged to examine the evidence and test what we observe and what we have been told:

1 Thessalonians 5:19-21
Do not quench the Spirit; do not despise prophetic utterances. But examine everything carefully; hold fast to that which is good…

1 John 4:1
Beloved, do not believe every spirit, but test the spirits to see whether they are from God; because many false prophets have gone out into the world.

In the end, God wants us to be convinced of the truth in such a way as to allow this truth to change our lives. God wants us to be convinced:

Romans 14:5
Let each man be fully convinced in his own mind.

2 Timothy 1:8-12
Therefore do not be ashamed of the testimony of our Lord, or of me His prisoner; but join with me in suffering for the gospel according to the power of God, who has saved us, and called us with a holy calling, not according to our works, but according to His own purpose and grace which was granted us in Christ Jesus from all eternity, but now has been revealed by the appearing of our Savior Christ Jesus, who abolished death, and brought life and immortality to light through the gospel, for which I was appointed a preacher and an apostle and a teacher. For this reason I also suffer these things, but I am not ashamed; for I know whom I have believed and I am convinced that He is able to guard what I have entrusted to Him until that day.

2 Timothy 3:14
You, however, continue in the things you have learned and become convinced of, knowing from whom you have learned them…

When believers use their minds, investigate the evidence and become convinced, something wonderful happens; they have the courage to defend what they believe using the same logic and reasoning power that assisted them to faith in the first place:

1 Peter 3:15
…but sanctify Christ as Lord in your hearts, always being ready to make a defense to everyone who asks you to give an account for the hope that is in you, yet with gentleness and reverence…

Over the centuries, Christians in all disciplines of inquiry and discovery have used their reasoning powers to investigate the evidence. Christians are not irrational by nature and many Christians have been world leaders in their use of reason and rationality.

Great Christian Thinkers
While there may be 150 years worth of great atheist thinkers that can be paraded in front of us to justify the possible truth of naturalism and humanism, there are thousands of year’s worth of great Christian scientists and writers and thinkers who have reasoned to just the opposite conclusion. These were rational and reasonable CHRISTIANS who saw no conflict between the rational process of thoughtful examination and their belief in the existence of God. They saw no conflict between the pursuit of science and the pursuit of theology. In fact, they saw the two endeavors as inextricably connected.

That’s quite a list of great thinkers, and it is only a very small representation of theists who have managed to retain a belief in God while deeply exploring the truths they have learned through reason and scientific observation. But these great thinkers have done more than simply hold on to their faith; it was their faith in the existence of an orderly and all-powerful God that established the foundation from which they knew that science could be done in the first place!

Theists hold that our universe is the product of an orderly and rational God and as such, must certainly follow the laws of this orderly and rational law giver. For this reason, we should expect the universe to submit to certain universal constants that can be observed and tested. Perhaps this is why so many great scientific thinkers have been Christians. And these Christians certainly understand the connection between faith and reason.

Jesus Understood the Connection
And the greatest of theistic thinkers was, of course, Jesus Himself. We don’t tend to think of him as the smartest man who ever lived, but (as God Himself) that is exactly what he was (and is). Jesus understood the relationship between reason and faith. Over and over again he offered EVIDENCE that he was God and asked those who were watching to use their reason to connect the evidence to the truth.

John 10:37-38
“If I do not do the works of My Father, do not believe Me; but if I do them, though you do not believe Me, believe the works, so that you may know and understand that the Father is in Me, and I in the Father.”

Jesus gave us more than enough REASON to believe that He was who he said he was, and He never asked us to believe blindly. It’s important for us to understand that when Jesus asks us to have faith in Him, he is asking us to accept what he says on the basis of the evidence that He has given us. The Christian Faith is a reasonable faith:

• Unreasonable Faith: Believing in something IN SPITE of the evidence. We hold an unreasonable faith when we refuse to accept or acknowledge evidence that exists, is easily accessible and clearly refutes what we believe.
• Blind Faith: Believing in something WITHOUT any evidence. We hold a blind faith when we accept something even though there is no evidence to support our beliefs. We don’t search for ANY evidence that either supports or refutes what we are so determined to believe.
• Reasonable Faith: Believing in something BECAUSE of the evidence. We hold a reasonable faith when we believe in something because it is the most reasonable conclusion from the evidence that exists. The Bible repeatedly makes evidential claims. It offers eyewitness accounts of historical events that can be verified archeologically, prophetically and even scientifically. We, as Christians are called to hold a REASONABLE FAITH that is grounded in this evidence.

How Reason and Faith Co-Exist
Now it’s important to realize that theists are not the only people who employ ‘faith’ as they sort through and accept truth claims. All of us are comfortable accepting many propositions without clear or tangible definitive evidence. Trusting when you don’t have perfect evidence; this is the substance of ‘faith’, this is what it means to move and rely on ‘faith’. And all of us trust in something we cannot observe, or cannot confirm from direct physical evidence. As an example, both the theist and the atheist must trust in something they cannot see or confirm in order to explain the origin of life in the universe. Both sides may have good theories, both sides may build their case from the best circumstantial evidence available to them, but at the end of the day, both the theist and the atheist are going to have to place their confidence in something that cannot be observed or confirmed with direct physical evidence. Neither group was present at the point at which life began to observe the moment evidentially as eyewitnesses.

If we think of ‘faith’ in this way (as trusting in something that we cannot observe, confirm or demonstrate evidentially, even though other circumstantial evidence may make trusting ‘reasonable’), then all of us exert some form of faith to accept and live within our worldviews. With this notion of ‘faith’ in mind, it is clear that we exercise both reason AND faith in order to come to a belief in ANYTHING:

Reason and faith are not enemies, they are essential partners as we do our best to observe, make sense of, and live in the world around us.

But, Can Fallen Humans Really Trust Their Own Rationality?
Many Christians take a very different view of reason and ‘faith’ than I have offered here. After all, doesn’t the Bible teach that humans, in our fallen natural condition, will always deny the truth of the evidence they see related to the existence of God? Doesn’t the Bible clearly teach that the ‘natural man’ is wicked and cannot apprehend the things of God? Look at some sample verses that are often used to make this case:

Romans 8:5-8
For those who are according to the flesh set their minds on the things of the flesh, but those who are according to the Spirit, the things of the Spirit. For the mind set on the flesh is death, but the mind set on the Spirit is life and peace, because the mind set on the flesh is hostile toward God; for it does not subject itself to the law of God, for it is not even able to do so; and those who are in the flesh cannot please God.

Romans 1:18-24
The wrath of God is being revealed from heaven against all the godlessness and wickedness of men who suppress the truth by their wickedness, since what may be known about God is plain to them, because God has made it plain to them. For since the creation of the world God’s invisible qualities-his eternal power and divine nature-have been clearly seen, being understood from what has been made, so that men are without excuse. For although they knew God, they neither glorified him as God nor gave thanks to him, but their thinking became futile and their foolish hearts were darkened. Although they claimed to be wise, they became fools and exchanged the glory of the immortal God for images made to look like mortal man and birds and animals and reptiles.

1 Corinthians 2:12-14
We have not received the spirit of the world but the Spirit who is from God, that we may understand what God has freely given us. This is what we speak, not in words taught us by human wisdom but in words taught by the Spirit, expressing spiritual truths in spiritual words. The man without the Spirit does not accept the things that come from the Spirit of God, for they are foolishness to him, and he cannot understand them, because they are spiritually discerned.

John 6:44
“No one can come to me unless the Father who sent me draws him, and I will raise him up at the last day”

Isn’t the natural mind too depraved to understand the things of God? Aren’t humans incapable of understanding the truth of God’s existence unless God first acts to remove the intellectual barriers so they can see the truth? And if this is the case, isn’t it futile for us to be sharing evidence with people who, in their ‘natural’ condition, are going to reject the truth anyway?

Well let’s think about that for a second. While it is clear that no one comes to the Son unless the Father first draws them, and it is clear that our minds must first be renewed by God so that they can understand spiritual truths, it is also clear that these truths were delivered EVIDENTIALLY to eyewitnesses who then testified about them in the special revelation of the scriptures, and these truths are also available to us EVIDENTIALLY through the natural world that we live in. We observe and listen to the eyewitness accounts of scripture and to natural revelation using our empirical senses, and we appraise the evidence using our rational minds. Yes, God does ‘flip the switch’ and remove barriers that we construct to deny the truth, but He expects us to reason through the evidence once the switch has been flipped.

Live Above the Lies
When non-believers try to paint Christians as unthinking and irrational, they are simply trying to demonize those with whom they disagree. The truth is that while we may not agree on the conclusions reached by atheists, we theists HAVE used our reasoning powers in a rational way to look at the evidence. Not all atheists are rational, and not all Christians have been rational in their examination of the evidence either. But for rational, evidential theists who are committed to studying the truth of their worldview, reason and rationality have been essential to our faith.
