Present the Gospel
A dramatisation of John 20.19-31 using an imaginary conversation between Mary Magdalene and Thomas
Emphasise the chronology of the two events in this passage (they're a week apart) with the dramatic interlude: 'But that I can't believe.'
Read vv.19-23, perform the Interlude and then read vv.26-31.
You could also present the two parts of the reading dramatically, sharing it between four or more actors: a narrator, Jesus, Thomas, and up to ten disciples.
