Romans 3:23 "For all have sinned and fall short of the glory of God,"
1 John 1:10
"If we say that we have not sinned, we make him a liar, and his word is not in us."
Jer. 17:9, 10
"The heart is the most deceitful thing there is, and
desperately wicked. No one can really know how bad it is! Only the Lord knows!"
Psalm 14:2, 3
"The Lord looks down from heaven on all mankind to see if there are any who are wise, who want to please God. But no, all have strayed away; all are rotten with sin.
Not one is good, not one!"
Is. 64:5, 6.
"
We are all infected and impure with sin. When we put on our prized robes of righteousness we find they are but filthy rags."
It should be the goal of every Christian to “sin no more,” although we recognize that, while we are in the flesh, we will still stumble and we will sin. (
1 John 1:8).
God’s desire for each of us is to be holy as He is holy (
1 Peter 1:16). We still sin, but sin is no longer a lifestyle choice (
1 John 3:9–10). When we fail, we can come to God and ask forgiveness (
1 John 1:9;
1 Peter 4:1–2). And if we are truly God’s children, He will correct us, disciplining us when we need it (
Hebrews 12:6–11). His work is to conform us to the image of His Son (
Romans 8:29).
But to say and believe that we do not sin after coming to Christ is an un-Biblical thought and has no basis in the Scriptures as far as I can tell.
