I believe the reason Paul was chosen was because of the integrity of his heart towards God. Before he was called, Paul was someone that loved God and was serving God sincerely with all his heart albeit ignorantly. He was faithfully carrying on God's work to the best of his understanding according to the Jews religion. His faith towards God was not in question. He was not a hypocrite as most of the learned Pharisees were. What Jesus did was to redirect his path to the right path and use him for the ministry.
I believe that the ten commandments as handed over to Moses is still valid today if interpreted spiritually. What changed is the methodology of fulfilling the law. Paul never said they are not applicable if we truly understand him well but not applicable as it is used to apply in the days of old. He used his arguments to defend his gospel of faith and in Romans he echoes Love is the fulfillment of the law.
I just noticed something about Paul as I was reading your post.....
Paul's life before and after meeting Jesus Christ on the road to Damascus is a picture of one living life under the Law of Moses verses one living life under the Law of Faith in Jesus Christ.
After meeting Jesus and being filled with the Holy Spirit, Paul no longer preached the Law of Moses but rather Jesus Christ as Savior, Messiah, Lord and King.....and even preached to the Gentiles.[/QUOTE]
I agree. I think it is a matter of knowing and understanding the Truth. Before Paul was called, though he was serving God with all his heart, he was doing that in ignorance of the truth of God and thus, in unbelief. After meeting Jesus, he knew the truth, lived and taught in accordance with the truth. I believe he taught the law but not in the way and manner it was being taught under their Torah.
The bible tells us in 1 John 5:20 that Jesus Christ has come and has given us an understanding of the true God, that we may know him that is true----- Christians follow, serve and worship God as declared by Jesus. So, Paul would not have taught differently. Jesus brought to man a higher understanding of God than Moses declared. God did not reveal himself fully to Moses as we read in Exodus 33:18 - 23. As a result, Moses could not express or declare God’s fullness neither can any of us know and express the fullness of God on the basis of His dealings with Moses and the Israelites of old even though Moses was a true servant and Prophet of God. Their lives serve as lessons to us. As St Paul said, the Levitical Priesthood cannot lead us to Perfection. The gifts and sacrifices of the old covenant could not make him that did the service perfect as pertaining to the conscience (Hebrews 9:9)
The issue to me is not about preaching or teaching the law, it is about knowing and understanding the Truth. The ten Commandments that say we should not commit adultery or murder or bear false witness against another person are as valid today as they have ever been. Adultery, murder etc. remain as sinful as they were before the coming of Jesus Christ. The application differs. The understanding differs. Under the law for instance, it is said, stone any woman that is caught in adultery. But we know what happened when the Pharisees brought a woman caught in adultery to Jesus. We learnt about the grace (love and kindness) of God, forgiveness, judgment and a whole lots of things but above all, we learnt that sin is still sin whether under the law or under grace as he told the woman --go and sin no more. There is need to become a new creature.
It is all about achieving the righteousness of God here on earth which we cannot attain through the law for reason I have mentioned above, and others which Paul also enumerated in his letters. We can only be perfect (holy and blameless) which God our father enjoins us to be through the faith of our lord Jesus Christ and not through the law of Moses. Through faith, the law is fulfilled not jettisoned. Through faith, the Holy Spirit walking with us teaches and gives us the true understanding and meaning of the law the way Jesus wants us to understand them
I may have exceeded the word limit, so I stop.
