Let's examine this:
Gal 4:4 "But when the time had fully come, God sent his Son, born of a woman, born under law, 5 to redeem those under law...."
Christ came and joined Himself to our humanity and in so doing He, as the Son of Man, was born under law in order that He could legally redeem those under law.
So Christ came to save the human race from under law, but not by doing away with the law. Instead He took upon His sinless Deity our fallen human life. On the cross Christ came under the curse of the law. That wouldn't be possible if the law were "revoked".
Now turn to Gal 3:13 "Christ redeemed us from the curse of the law by (doing away with the law)?
No, that's not what the Bible teaches.
"Christ redeemed us from the curse of the law by becoming a curse for us".
If you do away with the law then Christ's death for sinners becomes meaningless.
If Christ did away with the law then sinful mankind does not need to be redeemed from under its curse.
Clearly Christ came to deliver us from under law, but He didn't do this by "revoking" the law.
If you still don't buy what I am saying turn to Matthew 5:17
"Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them. 18 I tell you the truth, until heaven and earth disappear, not the smallest letter, not the least stroke of a pen, will by any means disappear from the Law until everything is accomplished."
Has the world we live in come to an end? No! Therefore the law of God is alive and well.
Does that mean the believer is under the law's jurisdiction.
No!
Why? To be under law is death for all of us are a bunch of sinners, even though we are growing in grace.
Therefore, to legally redeem us from under law, Christ had to assume your life 2000 yrs ago. He did this by assuming the life we all share (Adam's life) and when the Son of Man died, you too died in Him.
Don't believe me?
Rom 6:6 ...."our old self (our old life from Adam) was crucified with him so that the body of sin might be done away with...."
Rom 7:4 "you (your life from Adam) also died to the law (the law demanded your death) through the body of Christ..."
So the law has not been abolished. Instead the law has been legally satisfied or fulfilled. Since your old life died the curse, the law has been satisfied and it no longer recognizes you as living.
Since you died with Christ the law no recognizes you as living. The law has no jurisdiction over the dead, just the living. A Christian has died to the law in Christ and therefore the law can't touch him.
Romans 7:6 " ...by dying to what once bound us (the law), we have been released from the law so that we serve in the new way of the Spirit, and not in the old way of the written code (i.e., obey & live, disobey & die)."
