Romans 14:1, 4, 12, 22

Now him that is weak in the faith receive, not to the determining of questions of reasoning.

Who art thou that judgest the servant of another? to his own master he stands or falls. And he shall be made to stand; for the Lord is able to make him stand.

So then each of us shall give an account concerning himself to God.

Hast thou faith? have it to thyself before God. Blessed is he who does not judge himself in what he allows.
