Willing sin means we have not surrendered our hearts to God.842 814
That is not what this says: For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins,
It does not say "all" our sin....it specifically says "willfully"...
If we continue in life not having died to sin, we risk losing our redemption.
Sin is always tempting us. We must resist all sin.
If we love Him we keep His commandments.
So far, I have yet to see that the fourth commandment has been excluded.
