John 20

30 Jesus performed many other signs in the presence of His disciples, which are not written in this book. 31 But these are written so that you may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in His name.

Luke 24

38 “Why are you troubled,” Jesus asked, “and why do doubts arise in your hearts? 39 Look at My hands and My feet. It is I Myself. Touch Me and see—for a spirit does not have flesh and bones, as you see I have.” 40 And when He had said this, He showed them His hands and feet.
