At the cross, though Jesus had no sin of his own, the Lord laid on him the iniquity of us all. Jesus suffered the penalty we each deserve. But then, the power of God raised him! And we celebrate the risen Christ, for there is no salvation without the crucifixion and resurrection of Jesus Christ. That salvation, "God's grace in Christ, received by faith, is the fountain from which everything good flows" (Dennis Johnson). Believe in Christ, and you will be saved.
The angel proclaims to Mary God's unfolding plan, a plan that will change the world forever. It is an announcement that declares the greatness of God, the love of God, and our need for a savior.
Jesus has come as King and Savior to bring forgiveness and life and joy and freedom. Few people recognized his coming as the appearance of the Christ. We are to see Jesus as our life and our hope and our freedom.
