There is a wrong idea that the belief of the resurrection was slow to come to the church. This idea is set forth by those who would say the resurrection was a story invented by the church, but the opposite is actually true. In fact, the resurrection was not welcome in the church, according to the account of Thomas here in John 20. Jesus appeared five times the first day of His resurrection, then there are just five more appearances in the next 40 days, and only one more when He appeared to Saul on the Damascus road. God uses Thomas not as a negative example, but to show that the resurrection was real. Thomas believed because he saw the risen Christ. We have his testimony!
