18 "If the world hates you, be aware that it hated me before it hated you. 19 If you belonged to the world, the world would love you as its own. Because you do not belong to the world, but I have chosen you out of the world-therefore the world hates you. 20 Remember the word that I said to you, "Servants are not greater than their master.' If they persecuted me, they will persecute you; if they kept my word, they will keep yours also. 21 But they will do all these things to you on account of my name, because they do not know him who sent me. 22 If I had not come and spoken to them, they would not have sin; but now they have no excuse for their sin. 23 Whoever hates me hates my Father also. 24 If I had not done among them the works that no one else did, they would not have sin. But now they have seen and hated both me and my Father. 25 It was to fulfill the word that is written in their law, "They hated me without a cause.'
26 "When the Advocate comes, whom I will send to you from the Father, the Spirit of truth who comes from the Father, he will testify on my behalf. 27 You also are to testify because you have been with me from the beginning.

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.

The blessed Spirit will maintain the cause of Christ in the world, notwithstanding the opposition it meets with. Believers taught and encouraged by his influences, would bear testimony to Christ and his salvation.
