John 15:12 - Ellicott's Commentary On The Whole Bible

This is my commandment. — Comp. Note on John 13:34. In John 15:10 keeping of His commandments was laid down as the means of abiding in His love. He now reminds them that that which was specially the commandment to them was love to one another. Love to God is proved by love to mankind. The two great commandments of the law are really one. “If a man love not his brother whom he hath seen, how can he love God whom he hath not seen?”
