15 I do not call you servants any longer, because the servant does not know what the master is doing; but I have called you friends, because I have made known to you everything that I have heard from my Father. 16 You did not choose me but I chose you. And I appointed you to go and bear fruit, fruit that will last, so that the Father will give you whatever you ask him in my name. 17 I am giving you these commands so that you may love one another.
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.

Commentary on John 15:9-17
(Read John 15:9-17)
Those whom God loves as a Father, may despise the hatred of all the world. As the Father loved Christ, who was most worthy, so he loved his disciples, who were unworthy. All that love the Saviour should continue in their love to him, and take all occasions to show it. The joy of the hypocrite is but for a moment, but the joy of those who abide in Christ's love is a continual feast. They are to show their love to him by keeping his commandments. If the same power that first shed abroad the love of Christ's in our hearts, did not keep us in that love, we should not long abide in it. Christ's love to us should direct us to love each other. He speaks as about to give many things in charge, yet names this only; it includes many duties.
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.
