20 Remember the word which I said unto you, The bondman is not greater than his master. If they have persecuted me, they will also persecute you; if they have kept my word, they will keep also yours. 21 But they will do all these things to you on account of my name, because they have not known him that sent me.
Matthew Henry's Commentary on John 15:20-21
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.
