Resurrection rearranges everything. It challenges us to see life as an adventure that demands new actions on our part. Resurrection compels us to look at the world with eyes of hope. Resurrection invites us to move into a future where God's love prevails over the cynical finality of death. Resurrection life is always busy changing things.
Resurrection changes everything.
Thomas was fearful, so fearful. To believe in resurrection life was to open himself to new disappointments and heart breaks. It meant having to hope for something different from life than just death and disappointment. If it turned out that Jesus was not really resurrected, what a cruel hoax that could only lead Thomas to the worst kind of despair. Fear is overcome for Thomas when Jesus comes looking for Thomas and shows him he is more than just a figment of the other disciples' imaginations.
