Repeatedly the New Testament tells us that we are not justified by the law.
“Justified” means to declare someone righteous. The law does not declare people righteous.
The law was not designed to make people righteous, nor to declare anyone righteous. The law was written to declare everyone a sinner!
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.
The law tells you what sin is and makes you guilty
Now we know that what things soever the law saith, it saith to them who are under the law: that every mouth may be stopped, and all the world may become guilty before God.
The law declares people to be sinners. Paul says in Romans 7 that the law actually stirs up the flesh to sin more. The law makes sin abound.
You can’t be justified by the law because the law could never declare anyone to be righteous. The law points out how unrighteous you are.
The law has NO POWER to make you righteous. If the law can’t make you righteous; then the law can’t declare you righteous.
The only way you can be truly declared righteous in God’s eyes is if something existed that could make you righteous!
That aint the law!
But it is the Gospel!
For as by one man’s disobedience many were made sinners, so by the obedience of one shall many be made righteous.
The Gospel declares you righteous because the Gospel makes you righteous, not just in God’s head or your head, but in actual conduct.
The law cannot do that because the law is weak through the flesh. It has no power to make you do anything right, therefore, it can never declare anyone righteous because before it; no one is righteous.
The law won’t justify you; the Gospel will. Come to the Gospel of Jesus Christ and be made righteous.
But God be thanked, that ye were the servants of sin, but ye have obeyed from the heart that form of doctrine which was delivered you. Being then made free from sin, ye became the servants of righteousness.
