18 If the world hateth you, ye know that it hath hated me before [it hated] you. 19 If ye were of the world, the world would love its own: but because ye are not of the world, but I chose you out of the world, therefore the world hateth you. 20 Remember the word that I said unto you, A servant is not greater than his lord. If they persecuted me, they will also persecute you; if they kept my word, they will keep yours also. 21 But all these things will they do unto you for my name's sake, because they know not him that sent me. 22 If I had not come and spoken unto them, they had not had sin: but now they have no excuse for their sin.

Commentary on John 15:18-25
(Read John 15:18-25)
How little do many persons think, that in opposing the doctrine of Christ as our Prophet, Priest, and King, they prove themselves ignorant of the one living and true God, whom they profess to worship! The name into which Christ's disciples were baptized, is that which they will live and die by. It is a comfort to the greatest sufferers, if they suffer for Christ's name's sake. The world's ignorance is the true cause of its hatred to the disciples of Jesus. The clearer and fuller the discoveries of the grace and truth of Christ, the greater is our sin if we do not love him and believe in him.
