Even when you don’t believe in God, God believes in you. This isn’t just my wishful thinking: this is what happens in Scripture to faithful doubters. Sarah laughed at the absurdity of God promising to give her a son, and Isaac was born. After the crucifixion, Jesus appeared to show his hands and side to a doubtful Thomas. Paul doubted Christianity so much that he worked to stamp it out; God called him to build the church. Doubt doesn’t mean that God has abandoned you. It could, however, mean that God is calling you.
