We know why the people were baptized, but why was Jesus baptized? He didn’t need repentance or forgiveness. The answer is that He did it for us. The reason God sent His Son into the world is to fulfill all righteousness for us, to do what we could not do. The whole of Jesus’ life, everything He did and said, was one great offering to the Father in our stead to fulfill all righteousness for us. With our righteousness fulfilled in Jesus and given to us in Baptism, our hearts now overflow with thanksgiving and praise.
