Andrew Peterson is a Christian musician and novelist, and one of my favorites. He’s known for his song Is He Worthy? and for a wonderful series of four children’s books, The Wingfeather Saga.
This is one of the underlying themes throughout all of Scripture: despite our own unfaithfulness, God remains faithful. An appropriate response to God's unending grace and generosity is wonder. Peterson contrasts Jesus' words (why hast thou forsaken me?) with our own: why hast thou accepted me?
