Why Is Evidence Important for Faith?

Why Is Evidence Important for Faith?

[God] 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 given to us in Christ Jesus… to which I was appointed a preacher, an apostle, and a teacher of the Gentiles… I know whom I have believed and am persuaded that He is able to keep what I have committed to Him until that Day. — 2 Timothy 1:9, 2 Timothy 1:11-12


Imagine a courtroom scene. At the head of the courtroom, behind a desk on an elevated platform, sits the judge. Positioned nearby is the court reporter, the clerk, and the bailiff. To the right is the jury. In the middle of the room, off to one side, is the lawyer who will be prosecuting the case. To the other side is the defendant and his attorney.

It is the job of the prosecutor to make his case in such a way that it leaves no reasonable doubt the defendant is guilty. To do so, he will call witnesses to testify and present relevant evidence. But now imagine that as the prosecutor steps up to make his opening arguments, he simply tells the judge and jury that they need to have faith that his convictions about the defendant are true. Chances are, not only would the prosecutor fail in his attempts to get the court to believe him in “blind faith,” but he would also likely get thrown off the case.

What is interesting is that many Christians today treat their faith this same way. Some even believe this type of blind faith is required… that they are never supposed to have any doubts about God, or the Bible, or the doctrines they learned in church. German philosopher and atheist Friedrich Nietzsche criticized Christians for this very reason when he wrote, “Christianity has done its utmost to close the circle and declared even doubt to be sin. One is supposed to be cast into belief without reason, by a miracle, and from then on to swim in it as in the brightest and least ambiguous of elements… What is wanted are blindness and intoxication and an eternal song over the waves in which reason has drowned.”1

The truth is that Christianity never demands blind faith.

Furthermore, by taking on the role of the prosecutor and investigating the claims of the Bible, we find that God does provide enough evidence for rational belief. In fact, author Lee Strobel, a former journalist and skeptic, found after conducting his own investigation of Christianity, “The conclusion was compelling, an intelligent entity has quite literally spelled out the evidence of his existence through the four chemical letters in the genetic code. It’s almost as if the Creator autographed every cell.”2

God has not provided exhaustive knowledge of His existence, but He has given sufficient knowledge for those with an open heart and mind. In this session, we will take the first step on this journey to discovery by looking at why evidence is so important for faith.3


If you or any of your group members are just getting to know one another, take a few minutes to introduce yourselves. Next, begin by discussing one of the following questions:

  • Why is it important to have evidence to back up your belief in something? When are some times that you put your faith in something that later proved to not be worthy of your trust?


  • What is the single biggest question about truth, the Bible, or Jesus that you find people struggle with today? What evidence are you hoping God provides to you during this study to answer that question?


Invite someone to read aloud the following passage from 1 Peter 3:15–17. Listen for fresh insight and then share any new thoughts with the group using the questions that follow.

Sanctify the Lord God in your hearts, and always be ready to give a defense to everyone who asks you a reason for the hope that is in you, with meekness and fear; having a good conscience, that when they defame you as evildoers, those who revile your good conduct in Christ may be ashamed. For it is better, if it is the will of God, to suffer for doing good than for doing evil.

According to this passage, what should believers in Christ be ready to defend?

What traits should you display when sharing the evidence for your faith?

Which of these two is harder for you to maintain when you are in the midst of defending your beliefs? Why?

What apologetics is all about is clearing away the stumbling blocks that people have on their journey to Christ. It is a way of loving other people.

Christianity is a historical and testable faith. One thing that separates Christianity from other religions is that it is based on truth. If you follow the evidence, it will lead you to truth.

The Bible does not teach that you should have blind faith. Rather, the biblical pattern is that God does some kind of miracle or reveals himself, which gives people knowledge, and then they are called to exercise an examined and intelligent faith in Him.

Apologetics simply means to be ready at all times to give a reason for the hope that you have found in God, the Scriptures, and the Christian story.

Apologetics is not a recent phenomenon in the church. Jesus reasoned with people, as did the apostle Paul and many of the first- and second-century church fathers.

Today, the internet has brought many challenges to the Christian faith, but it has also brought awareness to the great amount of historical evidence that reveals Christianity is true.

Five Reasons Why Apologetics is Important Today

  1. We are all apologists anyway: Apologetics is not listed as a spiritual gift for teachers, preachers, or evangelists, as though only some ought to become apologists. Rather, all Christians are called to be ready with an answer.
  2. Apologetics strengthens believers: When Christians learn good evidences for the truth of the Bible, for the existence of God, or how to respond to tough challenges to the faith, they gain confidence in their beliefs.
  3. Apologetics helps students hang on to their faith: Young people today have genuine intellectual questions — including questions about their faith. When these questions are not answered, many leave the church.
  4. Apologetics helps with evangelism: One of the key functions of apologetics is to respond to peoples’ questions and clear away any objections or doubts they have that hinder their trust in Christ.
  5. Apologetics helps shape culture: Apologetics questions come from both Christians and non-Christians — because they both live in the same cultures, and the same world influences their thinking.4


Take a few minutes with your group members to discuss what you just watched and explore these concepts in Scripture.

  1. Did you grow up in a church and family environment where you were told what to believe or in one where everything was questioned? How has this environment in which you were raised affected how you approach your faith in Christ today?
  2. Why is it important to know why you believe rather than just what you believe?
  3. Paul wrote, “Do your best to present yourself to God as one approved, a worker who does not need to be ashamed and who correctly handles the word of truth” (2 Timothy 2:15 NIV). What are practical ways you can “correctly handle the word of truth” today?
  4. Why do you think popular culture (and even many Christians) embrace “blind faith”? What are some of the problems with this approach to faith?
  5. What is the difference between intelligent faith and blind faith? Based on the words of 1 Peter 3:15, which do you think Scripture teaches you to pursue?

6.How can knowing the evidence behind what you believe about Christ help you to remove any stumbling blocks that others might have in their journey toward faith in Jesus?


Wrap up your time by taking a few moments to pray together. Here are a few ideas of what you could pray about based on the topics of this session:

  • Ask God to give you a hunger and a joy to know truth.
  • Express your willingness to pursue the evidence for your beliefs… wherever that might lead.
  • Pray for the courage to pursue an intelligent faith over a blind
  • Tell God your desire for answers to the big questions with which you are struggling.
