He is the Christ, the Messiah, not because of his perfect obedience to the law. His obedience was to God which brought him death at the hands of the law-keepers. The Gospel of Luke reminds us of the life that came to be revealed in the resurrection of Jesus. He was obedient to the will of God and was subjected to death by the law-keepers, but God delivered on his promise to reveal the kingdom of life. Now we too are free to take up our own cross, to give up our lives when it is bound by law and to turn to God in faith.
Faith is no longer a reliance on law.
Faith is trust in the promise that the value of our lives lies not in our performance but in God's performance. Everyone knows something of this in our Age of Achievement. We struggle day in and day out to give ourselves value. We accomplish this, then that. The law of success determines our value.
