The angel came to her and said, “Greetings! The Lord has blessed you and is with you.” But Mary was very startled by what the angel said and wondered what this greeting might mean. The angel said to her, “Don’t be afraid, Mary; God has shown you his grace.”
Luke 1:28-30 (NCV)
God’s grace is a special gift that we do not deserve. No matter who is against us, God is for us, do not surrender to unbelieving fear.
