15 No longer do I call you servants, for the servant does not know what his master is doing; but I have called you friends, for all that I have heard from my Father I have made known to you. 16 You did not choose me, but I chose you and appointed you that you should go and bear fruit and that your fruit should abide; so that whatever you ask the Father in my name, he may give it to you. 17 This I command you, to love one another.
18 "If the world hates you, know that it has hated me before it hated you. 19 If you were of the world, the world would love its own; but because you are not of the world, but I chose you out of the world, therefore the world hates you. 20 Remember the word that I said to you, 'A servant is not greater than his master.' If they persecuted me, they will persecute you; if they kept my word, they will keep yours also. 21 But all this they will do to you on my account, 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 He who hates me hates my Father also. 24 If I had not done among them the works which 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.
