Luke 6:37 FNV
God has reserved three prerogatives royal to Himself — vengeance, glory, and judgment. As it is not safe for us, then, to encroach upon God's royalties in either of the other two — glory or vengeance — so neither in this, of judgment.
We have no right to judge; and so our judging is usurpation. (Sanderson)
No man can justly censure or condemn another, because, in fact, no man truly knows another. Further, no man can judge another, because no man knows himself.
The Vicar of Gravenhurst, in his position of parish priest, owns himself compelled to confess that the best people are not the best in every relation of life, and the worst people not bad in every relation of life; so that with experience, he finds himself growing lenient in his blame, if also reticent in his praise. "Again and again I say to myself that only the Omniscient can be the equitable judge of human beings, so complicated are our virtue with our failings, and so many are the hidden virtues, as well as hidden vices, of our fellow-men." (Jacox)
We may err in our judgment; and so our judgment is rashness. We take things the worse way when we judge: and so our judging is uncharitable. We offer occasion of offense by our judging; and so our judging is scandalous (Deuteronomy 32:35; Isaiah 41:8; Romans 12:10; Romans 14:4). (Sanderson)
