John 15:18-21

Verse 18. If the world hate you. The friendship of the world they were not to expect, but they were not to be deterred from their work by its hatred. They had seen the example of Jesus. No opposition of the proud, the wealthy, the learned, or the men of power, no persecution or gibes, had deterred him from his work. Remembering this, and having his example steadily in the eye, they were to labour not less because wicked men should oppose and deride them. It is enough for the disciple to be as his Master, and the servant as his Lord, Mt 10:25.

(u) "If the world hate you" 1Jn 3:13
Verse 19. If ye were of the world. If you were actuated by the principles of the world. If, like them, you were vain, earthly, sensual, given to pleasure, wealth, ambition, they would not oppose you.

Because ye are not of the world. Because you are influenced by different principles from men of the world. You are actuated by the love of God and holiness; they by the love of sin.

I have chosen you out of the world. I have, by choosing you to be my followers, separated you from their society, and placed you under the government of my holy laws.

Therefore, &c. A Christian may esteem it as one evidence of his piety that he is hated by wicked men. Often most decided evidence is given that a man is the friend of God by the opposition excited against him by the profane, by Sabbath-breakers, and by the dissolute, 1Jn 3:13, Jn 7:7.

(v) "therefore the world hateth you" Jn 17:14
Verse 20. Remember the word that I said, &c. At their first appointment to the apostolic office. See Mt 10:24, 25.

(w) "Remember" Mt 10:24, Lk 6:40, Jn 13:16 (x) "if they have kept" Eze 3:7
Verse 21. My name's sake. On my account. Because you are my followers and possess my spirit. Jn 14:13.

Because they know not him that sent me. They will not believe that God has sent me. They do not so understand his character, his justice, or his law, as to see that it was fit that he should send his Son to die. They are so opposed to it, so filled with pride and opposition to a plan of salvation that is so humbling to men, as to be resolved not to believe it, and thus they persecute me, and will also you.

(y) "But all these things" Mt 10:22, 24:9
