1. Walking in the Spirit Does Not Nullify the Law

Many quote Romans 6:14 out of context:

For sin shall not have dominion over you: for ye are not under the law, but under grace.

They assume this means believers are no longer bound to keep God’s commandments, but the very next verse clarifies it:

What then? shall we sin, because we are not under the law, but under grace? God forbid. (Romans 6:15)

Since sin is the transgression of the law (1 John 3:4), this means grace does not exempt us from keeping the law—it empowers us not to break it.

2. Not Under the Law = Not Under Its Penalty

To be “under the law” means to be under its condemnation due to sin. When we walk in the Spirit, we do not transgress the law, so the penalty of the law (death) does not apply to us.

Paul confirms this in Galatians 5:16-18:

This I say then, Walk in the Spirit, and ye shall not fulfil the lust of the flesh.
For the flesh lusteth against the Spirit, and the Spirit against the flesh: and these are contrary the one to the other: so that ye cannot do the things that ye would.
But if ye be led of the Spirit, ye are not under the law.

This does not mean that believers are free from obeying God’s laws—it means that if we are walking in the Spirit, we will not break them!

3. Wilful Sin After Knowledge of the Truth

Hebrews 10:26-29 is one of the strongest warnings in the New Testament:

For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins,
But a certain fearful looking for of judgment and fiery indignation, which shall devour the adversaries.
He that despised Moses’ law died without mercy under two or three witnesses:
Of how much sorer punishment, suppose ye, shall he be thought worthy, who hath trodden under foot the Son of God, and hath counted the blood of the covenant, wherewith he was sanctified, an unholy thing, and hath done despite unto the Spirit of grace?

This passage is often ignored because it directly contradicts the false doctrine that grace covers wilful sin after coming to the truth. The Torah itself made a clear distinction between sins committed in ignorance versus sins committed wilfully:

Ignorant Sin Was Forgiven

And if any soul sin through ignorance, then he shall bring a she-goat of the first year for a sin offering. (Numbers 15:27)

Wilful Sin Had No Atonement

But the soul that doeth ought presumptuously… the same reproacheth the LORD; and that soul shall be cut off from among his people. (Numbers 15:30)

The same principle is upheld in the New Covenant. Christ’s sacrifice atones for all sins before we come to Him, but after we have knowledge of the truth, there is no more sacrifice for wilful sin.

4. The Danger of Twisting Paul’s Writings

Peter warned that Paul’s letters are often misunderstood and misused to promote lawlessness:

As also in all his epistles, speaking in them of these things; in which are some things hard to be understood, which they that are unlearned and unstable wrest, as they do also the other scriptures, unto their own destruction. (2 Peter 3:16)

Many churches teach that “Christ fulfilled the law, so we don’t have to keep it.” But as you said, where in Scripture does it say that because Christ fulfilled the law, we do not have to fulfill it?

Instead, the Scriptures say:

Love is the fulfilling of the law. (Romans 13:10)
And hereby we do know that we know him, if we keep his commandments. (1 John 2:3)

This shows that believers must still fulfill the law, just as Yahusha did.

5. No “Habitual Sin” Loophole

Some try to argue that Hebrews 10:26 only applies to “habitual” sin. But the passage makes no such distinction. The phrase “if we sin wilfully” is a broad statement that covers any deliberate disobedience after knowing the truth.

There is only one way out of this condemnation: repentance. If we confess our sins, God is faithful to forgive (1 John 1:9), but this does not mean we can knowingly sin and expect to be forgiven without true repentance.

Final Conclusion

1. Walking in the Spirit does not mean we are no longer subject to God’s laws. It means we will keep them naturally.
2. Not being under the law means we are no longer under its penalty, not that we are free to break it.
3. If we sin wilfully after knowing the truth, there is no more sacrifice for sins, and we become God’s adversary (Hebrews 10:26-29).
4. There is no loophole that allows for occasional wilful sin without consequences.
5. Many misunderstand Paul’s writings and twist them to justify lawlessness (2 Peter 3:16).
