The First Luminous Mystery: The Baptism of the Lord
Our Lord, though innocent, takes on our sins as He enters the water of Jordan and is baptized by John. His mission of our salvation is blessed by the Father's praise and the Spirit's descent. Ask Our Lady to help you pray this decade, pondering the light that comes from submission to the will of God.
