‘The core of faith: seeing what can’t be seen’ (John 20:24-31)

When Jesus appeared to the disciples after the resurrection, Thomas had not been with them and refused to believe their testimony. However, when Jesus appeared to Thomas and proved that he was alive, Thomas’ doubts soon evaporated and he freely confessed his faith. John’s purpose in writing what he did about Jesus was for this very purpose; that we too may believe God’s testimony concerning His Son.
