18 If you are hated by the world, keep in mind that I was hated by the world before you. 19 If you were of the world, you would be loved by the world: but because you are not of the world, but I have taken you out of the world, you are hated by the world. 20 Keep in mind the words I said to you, A servant is not greater than his lord. If they were cruel to me, they will be cruel to you; if they kept my words, they will keep yours. 21 They will do all this to you because of my name—because they have no knowledge of him who sent me. 22 If I had not come and been their teacher they would have had no sin: but now they have no reason to give 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.
