If all of God’s laws were nailed to the cross, then no one after that could be a sinner because it would be impossible to sin. If no one sinned, we wouldn’t need Jesus Christ, but we do need Him because sin is still here and so are the laws that are being broken.

The law that was nailed to the cross and taken out of the way which was against us is “the wages of sin is death” law. It is only taken away for everyone who continues to walk in confession and repentance, those walking after the Spirit and NOT after the flesh (that’s a conditional statement). If we are walking after the flesh then we are not IN Christ because the scripture speaks specifically and defines exactly what it looks like to be IN Christ.

Romans 8:1-2
“There is therefore now no condemnation to them which are IN Christ Jesus, who walk not after the flesh, but after the Spirit. For the law of the Spirit of life in Christ Jesus hath made me free from the law of sin and death.”

Did you recognize a law that’s still in effect? “For THE LAW of the Spirit of life in Christ Jesus”; If we didn’t have that law in effect we couldn’t have eternal life and we would still be dead in our sins.

To understand God and what He’s saying takes our knowing the scriptures, putting them all together logically and then using deductive reasoning (it’s like math).

Assumption to test:
“All of God’s laws are ended and done away with and we aren’t under His laws.” – man’s doctrine

If there are no laws, then there would be no sin. – God

1John 3:4
“Whosoever committeth sin
transgresseth also the law:
for sin is the transgression of the law.”

Romans 4:15
“ …for where no law is,
there is no transgression.”

1John 1:8-10
“If we say that we have no sin,
we deceive ourselves,
and the truth is NOT IN us.

If we confess our sins,
He is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.

If we say that we have not sinned,
WE MAKE HIM A LIAR,
and His word IS NOT IN us.”

1 Corinthians 9:21
“ … being not without law to God,
BUT UNDER THE LAW to Christ…”

The same man who taught us that we were not under the law but under grace was speaking of the wages of sin is death law. We can know that for sure because he went onto say many other things that make it clear that the law is still in effect and binding on everyone including born again believers including himself.

Romans 8:12-13
“Therefore, brethren, we are debtors, not to the flesh, to live after the flesh. For if ye live after the flesh, ye shall die: but if ye through the Spirit do mortify the deeds of the body, ye shall live.”

1Corinthians 9:27
“But I keep under my body, and bring it into subjection: lest that by any means, when I have preached to others, I myself should be a castaway.”

2Corinthians 5:9
“Wherefore we labour, that, whether present or absent, we may be accepted of Him.”

1Corinthians 9:25
“And every man that striveth for the mastery is temperate in all things. Now they do it to obtain a corruptible crown; but we an incorruptible.”
