In the Gospel of John, when Jesus appears for the second time after the Resurrection, Thomas is present. He doubted the word of his companions that Jesus had risen form the dead.
Doubt matters. The eventual faith of Thomas is as strong and relevant as the persistence of Mary Magdalene; both are essential.
How do I deal with doubt? Am I honest with myself, God, and others about my fears? Do I leave room to grow? O Holy Spirit, grant me a confident faith. May I face doubt with courage and as an opportunity to grow.
