Romans 14:1, 4, 12, 22

But him that is weak in faith receive ye, yet not to doubtful disputations.

Who art thou that judgest the servant of another? to his own lord he standeth or falleth. Yea, he shall be made to stand; for the Lord hath power to make him stand.

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

The faith which thou hast, have thou to thyself before God. Happy is he that judgeth not himself in that which he approveth.
