Do the Ten Commandments still apply under the new covenant today?

[Davy]

I'm not "in the flesh"

Do just one little mess up in future sin, and yes you are, right back to being under the law.

You apparently have not studied your Bible enough to understand the difference between our being here in a flesh body vs. our hope for the future glory to come. Apostle Paul often spoke in terms of the glory that is still yet to come, and many mistake that as already having arrived, when he never taught that it did, lot of brethren just 'assume' that. And here's an example of Apostle Paul showing that future glory has not yet arrived today...

1 Tim 1:8-11
8 But we know that the law is good, if a man use it lawfully;

9 Knowing this, that the law is not made for a righteous man, but for the lawless and disobedient, for the ungodly and for sinners, for unholy and profane, for murderers of fathers and murderers of mothers, for manslayers,

10 For whoremongers, for them that defile themselves with mankind, for menstealers, for liars, for perjured persons, and if there be any other thing that is contrary to sound doctrine;

11 According to the glorious gospel of the blessed God, which was committed to my trust.
KJV

Like Apostle Paul taught in Galatians 3, walk by The Spirit and one will not be doing anything that is against God's laws.

But walk by our 'flesh', and not by The Spirit, then one brings theirself back under God's laws. Do we see some Christian brethren sometime falling to acts of following their flesh today. YES! it is STILL going on today! And it will continue... to happen unto the day of Christ's future coming when we all will put off these houses of flesh.

What Paul said above to Timothy confirms that many of God's laws are STILL in effect for the unrighteous and ungodly and sinner. But your mind apparently dwells in some illiterate preacher's la,la land instead of the written Word of God. The doctrine of 'once saved, always saved' is a doctrine from man, not from God.

Do just one little mess up in future sin, and yes you are, right back to being under the law.

IF I were to sin, I'll use the Lord's prescription to be cleansed of ALL unrighteousness and remain in Christ NOT being under the law of sin and death

Proverbs 28:13
He that covereth his sins shall not prosper: but whoso confesseth and forsaketh them shall have mercy.

1 John 1:9
If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.

Notice the term "cleansed of ALL unrighteousness"???

You apparently have not studied your Bible enough to understand the difference between our being here in a flesh body vs. our hope for the future glory to come.

You apparently have not studied your Bible enough to understand that Christians are to live as being be crucified with Christ allowing the Holy Spirit to live in them

Galatians 2:20
I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me.

Romans 8:9-11
But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his.
And if Christ be in you, the body is dead because of sin; but the Spirit is life because of righteousness.
But if the Spirit of him that raised up Jesus from the dead dwell in you, he that raised up Christ from the dead shall also quicken your mortal bodies by his Spirit that dwelleth in you.

Only those that allow the Lord to live in them leading them are actual Christians:

Romans 8:14
For as many as are led by the Spirit of God, they are the sons of God.

Apostle Paul often spoke in terms of the glory that is still yet to come

I never said I had received my glorified body as of yet.

I did say I yield my life to the Holy Spirit allowing Him to live in me and leads me in all aspects of my life.

It's called being Spirit filled which is something actual Christians walk in. You should get Spirit filled!

The doctrine of 'once saved, always saved' is a doctrine from man, not from God.

You false doctrine continues as you apparently claim Christians can walk after the flesh and still be saved.

That's doctrines of devils you are walking in son!

You should get back to the whole counsel of God and repent of your false doctrines as quickly as possible!
