What is the Purpose of the Law?

COME TO THE LORD - NOT TO THE LAW

One of the Key Differences between Biblical Christianity and Mormonism is their teaching that Salvation is by Faith alone and not by Faith plus Works. 

James 2:14, 20: "What doth it profit, my brethren, though a man say he hath faith, and have not works? Can faith save him? ...But wilt thou know, O vain man, that faith without works is dead?"

In this passage, James is refuting the idea that a person can have a true faith without producing any good works. He is emphasizing the point that genuine faith in Christ will produce a changed life and good works. James is NOT saying that justification by faith plus works creates salvation, but rather, he is teaching that a genuine faith will produce good works in the life of a believer. If a person claims to be a believer but has no good works, it is likely that this person doesn't have genuine, saving faith. 

THE PURPOSE OF THE LAW - To make us Conscious of our Sin - The Law Cannot Save Us. Only the Grace of Jesus Christ saves us.

Romans 3:20, 22: "Therefore by the deeds of the law there shall no flesh be justified in his sight: for by the law is the knowledge of sin. ...Even the righteousness of God which is by faith of Jesus Christ unto all and upon all them that believe.
