Many give Thomas a hard time for wanting to see the resurrected Jesus before he believed. Some even call him “Doubting Thomas” to illustrate his skepticism. However, Thomas’ doubt is powerful evidence for the resurrection of Jesus Christ.
Paul explains to the Corinthians that the whole gospel hangs on the resurrection of Jesus. If the resurrection did not happen, then Jesus was not the Son of God and His sacrifice was void.
12 Now if Christ is preached that He has been raised from the dead, how do some among you say that there is no resurrection of the dead? 13 But if there is no resurrection of the dead, then Christ is not risen. 14 And if Christ is not risen, then our preaching is empty and your faith is also empty. (1 Cor. 15:12-14)
If Jesus had not risen from the dead then He was not the Son of God. He would have been just a normal man that was executed. If He were not the Son of God, then His death was not the perfect sacrifice. If He were not the perfect sacrifice, then our sins have not been forgiven. In this conclusion, we are all still dead in our sins, unless Jesus rose from the dead. A person cannot claim that he is a Christian and that he does not believe Jesus rose from the dead. Both beliefs contradict each other. If someone wanted to dismantle Christianity he would need to prove that there was not a resurrection. Sadly for people like that, for the past 2000 years no one has been able to present any evidence against it.
Still, some will make the case that the Apostles were delusional. They argue that they did not see the resurrected Jesus like they claim as if they were foolish men who would believe anything. Thomas’ story is a powerful defense against that argument. Why? Thomas was a skeptic. When the other disciples told Thomas that they had seen Jesus resurrected, he did not believe. It was not until he saw Jesus that he believed.
24 Now Thomas, called the Twin, one of the twelve, was not with them when Jesus came. 25 The other disciples therefore said to him, “We have seen the Lord.”
So he said to them, “Unless I see in His hands the print of the nails, and put my finger into the print of the nails, and put my hand into His side, I will not believe.”
26 And after eight days His disciples were again inside, and Thomas with them. Jesus came, the doors being shut, and stood in the midst, and said, “Peace to you!” 27 Then He said to Thomas, “Reach your finger here, and look at My hands; and reach your hand here, and put it into My side. Do not be unbelieving, but believing.”
28 And Thomas answered and said to Him, “My Lord and my God!” (John 20:24-28)
Thomas’ doubt proves that the Apostles were extremely rational and logical people. They did not believe that Jesus rose from the dead until they saw Him. Now, they have become eyewitness along with 500 others (1 Cor. 15:6). Thomas is further proof that the Apostles were reliable sources that provided powerful testimony so we too may believe that Jesus Christ was raised from the dead.
29 Jesus said to him, “Thomas, because you have seen Me, you have believed. Blessed are those who have not seen and yet have believed.” (John 20:29)
