I believe it. That settles it.
Faith is a life-long process of exploration and discovery, filled with detours and questions.
Thomas, like us, struggles with his faith as it develops. It is significant that Jesus invites him to touch his wounds, as he helps Thomas to come to a new understanding of his faith. In his struggle to believe, Thomas identifies with the wounds of Jesus - that is where our search also begins. We cannot understand God's glory, but we can understand something of his humanity, his suffering and death. Jesus teaches us that there are many dwelling places in God's mansion, that there is room for an unimagined variety of people in his kingdom.
