Romans 14:4

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. [We must avoid the sacrilegious presumption which condemns where God hath not condemned. Whether our brother in Christ stands in favor, so that his daily life and service are accepted of God, or whether he falls from grace, so that his labors are rejected, is a matter for the Master, and does not pertain to us servants. (Comp. 1 Corinthians 10:12; 1 Corinthians 16:13; 1 Thessalonians 3:8; Romans 8:33-34; Romans 11:22) A kindly, affectionate concern is commendable, but a censorious condemnation is forbidden. Moreover, the latter is useless and idle, for it is the duty of each disciple to please his Master, not his fellow-servant, and the Master is able to justify and will justify without consulting human accusers (Romans 8:33), or paying respect to man-made technicalities about indifferent things. Christ's ability to justify extends to even positive, inexcusable sin (Romans 3:26; John 8:11). If we could only learn that the consciences of others, though different, are as active and as exacting as our own, we would judge less and love more. Acting by contrary rule, if we find that any man's conscience varies from our own, we straightway conclude that he has no conscience at all, and hence is a proper subject for our condemnation, a culprit well within the bounds of our jurisdiction.]
