There seems to be a grave misimpression among skeptics regarding the meaning of faith. It is true that Christianity is a faith; it is also true that faith is needed for salvation. However, suggesting that Christians blindly believe something to be true without any evidence is grossly mistaken.
Faith is simply having confidence or trust in a person or thing; faith is not believing something to be true with no evidence. There is plenty of evidence to support Christianity: philosophical arguments, historical evidence, archaeological evidence, personal experience, and the facts concerning Jesus of Nazareth, are just a few examples.
Most, if not all, Christians have placed their faith in Christ, and because of that, their lives have been changed, and they have experienced God, personally, in an ongoing relationship with Him. When you experience God by means of the Holy Spirit living in you and working through you, this becomes a powerful piece of evidence for the Christian.
Sure you could say that people in other religions have also experienced God, but why should the Christian be robbed of what they know to be true based on somebody else’s experience? The truth is that they shouldn’t, just like we shouldn’t with anything else we experience in the world. These types of beliefs are what philosophers call properly basic, and until we have a defeater of those beliefs, we are justified in holding them.
Christianity has never been about believing something without evidence, even Jesus didn’t expect us to do that. Notice what He says, “. . . even though you do not believe me, believe the works, that you may know and understand that the Father is in me, and I in the Father” (John 10:38). In other words, look at the evidence; look at the miracles; look at the life and ministry of Jesus and how Old Testament prophecy could not have been fulfilled by any other person in history. Look at the well-established historical facts concerning Jesus: His death, burial, empty tomb, post-mortem appearances, and the unexpected rise of Christianity. These are all good reasons to believe that Christianity is at least based on some evidence.
When Paul wrote the Corinthians, he alluded to hundreds of people who could still testify to what they saw concerning the resurrected Christ (1 Corinthians 15:6). Even Thomas “the doubter” believed after seeing the resurrected Christ . . . and even he was willing to die for what he now knew to be true. As a matter of fact, even skeptical scholars believe that the apostles sincerely came to believe in the resurrected Christ after what they witnessed. The facts concerning Jesus of Nazareth are well-established and historically verifiable. If Christianity is false, we are left with an inexplicable explanation of those facts.
At the end of the day, there are good reasons to believe that Christianity is true, especially in light of all the evidence. Faith, on the other hand, is simply taking it one step further and believing that Jesus was who He claimed to be, trusting in His teachings, and believing that He will one day return, just like He said He would. This is what the apostles believed, taught, and, ultimately, died for. It is a reasonable faith based on well-established facts. Those who think otherwise, are simply out of touch with honest historical scholarship.
