I always thought that when Paul says the law of faith in Romans 3: 27 that he meant law as in principle. He is making a play on the word law. first he speaks of the law of Moses, meaning a set of rules. then he talks about the law of faith meaning not a set of rules based on faith but the principle of faith. I think that fits fully with the context of the entire chapter and Romans in general.
Jesus instructed everyone that if they truly loved Him, they would follow His set of rules. I know this teaching isn't popular with the religions of the world, but the scriptures certainly teach that we should not follow the "set of rules" from our own mind, instead, be renewed in the mind to follow another set of Rules created beforehand that we should walk in them.
What rules? or as Paul says it, "what Law"? The Law of Work's? So what is the Law of Works set forth for remission of sins? Love God with all your heart? Don't steal? Don't commit adultery?
No, the "Law of Works" Paul is speaking to,that was set forth for the remission of sins, was the Levitical Priesthood "Law of works" that the Jews had centered their religion around.
Woe unto you, scribes and Pharisees, hypocrites! for ye pay tithe of mint and anise and cummin, (Part of the Law of Works) and have omitted the weightier matters of the law, judgment, mercy, and faith: these ought ye to have done, and not to leave the other undone.
For they bind heavy burdens and grievous to be borne, and lay them on men's shoulders; but they themselves will not move them with one of their fingers.
But the Law of faith, Love God with all your heart, and the Law and Prophets which teach us how to do this, and the Law of faith, Love your neighbor as yourself, and the Law and Prophets which also teach us how to do this, is what Paul taught, and what we will be judged by.
13 (For not the hearers of the law are just before God, but the doers of the law shall be justified.
"circumcision is nothing, and uncircumcision is nothing, but keeping in Commandments of God.
This is why Jesus said the Law and Prophets are here as long as we are here. This is why Paul believes "ALL THINGS written in the Law and Prophets.
But a religion which transgresses the Commandments of God by their own religious traditions can't accept this. And even though Jesus pleads with them.
Jer. 6:16 Thus saith the LORD, Stand ye in the ways, and see, and ask for the old paths, where is the good way, and walk therein, and ye shall find rest for your souls.
They refuse to come to the Light. "But they said, We will not walk therein." As it is to this day.
God's "Set of rules" was a stumbling block for the Mainstream Preachers of Christ's time, and it is a stumbling block to the Mainstream Preachers of today. IMO.
