JJUSTIFIED BY FAITH IN CHRIST JESUS
To be declared righteous; to be in right relationship and thus accepted by God.
It is by faith in Jesus that individuals stand justified before God, not by trying to live by the OT rules and statutes.
Old Man vs New Creation
The Old person has been killed along with Christ and the requirements of the Law has been satisfied by the death of Christ, and punishment of Sin and death removed. Thus, I have been cleared of all charges and I have been made innocent and declared innocent at the same time
Living by Grace vs The Law
My life is now lived inside of Christ. I am no longer living by the power of what not to do in the flesh, but by the power of Jesus Christ on what to do.
Trying to please God by trying to fulfill the law communicates that you are not or have not really trusted in Christ Jesus by faith.
