We have no proof from John as to whether Thomas actually touched Jesus. There are those who say that Jesus commanded it, and therefore he had to have done it. However, It is just as likely that Jesus saying this and showing His hands and sides were enough for Thomas. It is likely that just seeing Jesus was enough. Thomas testifies to the truth of the resurrection. This is important because unless this truth is confirmed, the whole of the Gospel is in doubt. If Christ is not risen, we are in trouble (1 Corinthians 15:12-28).
