'Sinful' in the Bible

Certainly not! Let God be found true [as He will be], though every person be found a liar, just as it is written [in Scripture],“That You may be justified in Your words,And prevail when You are judged [by sinful men].”

This we know--that our old self was nailed to the cross with Him, in order that our sinful nature might be deprived of its power, so that we should no longer be the slaves of sin;

For when we were in the flesh, the sinful passions operated through the law in every part of us and bore fruit for death.

What should we say, then? Is the Law sinful? Of course not! In fact, I wouldn't have become aware of sin if it had not been for the Law. I wouldn't have known what it means to covet if the Law had not said, "You must not covet."

But sin seized the opportunity provided by this commandment and produced in me all kinds of sinful desires, since apart from the Law, sin is dead.

Was then that which is good made death unto me? God forbid. But sin, that it might appear sin, working death in me by that which is good; that sin by the commandment might become exceeding sinful.

For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh:

But he who is uncertain [about eating a particular thing] is condemned if he eats, because he is not acting from faith. Whatever is not from faith is sin [whatever is done with doubt is sinful].

Now I urge you, brothers, to watch out for those who create divisions and sinful enticements that oppose the teaching you have learned. Stay away from them,
