When busy with classes, it is the time for quotes. I am preparing a lesson on a section from the Sermon on the Mount. This quote summarizes all I wish to communicate:
"Jesus, the Son of God, who alone lives in perfect communion with him [God the Father], vindicates the law of the old covenant by coming to fulfill it. He was the only Man who ever fulfilled the law and therefore he alone can teach the law and its fulfillment aright. The disciples would naturally grasp that as soon as He told them, for they knew who He was…The only way for Him to fulfill the law is by dying a sinner’s death on the cross. There he embodies in his Person the perfect fulfillment of the law.
That is to say, Jesus Christ and he alone fulfills the law, because He alone lives in perfect communion with God. It is Jesus himself who comes between the disciples and the law, not the law which comes between Jesus and the disciples.” – Bonhoeffer. The Cost of Discipleship. pg 123
