Our Lord Jesus, by giving his disciples notice of trouble, designed that the terror might not be a surprise to them. It is possible for those who are real enemies to God's service, to pretend zeal for it. This does not lessen the sin of the persecutors; villanies will never be changed by putting the name of God to them. As Jesus in his sufferings, so his followers in theirs, should look to the fulfilling of Scripture. He did not tell them sooner, because he was with them to teach, guide, and comfort them; they needed not then this promise of the Holy Spirit's presence. It will silence us to ask, Whence troubles come? It will satisfy us to ask, Whither go they? for we know they work for good. It is the common fault and folly of melancholy Christians to look only on the dark side of the cloud, and to turn a deaf ear to the voice of joy and gladness. That which filled the disciples' hearts with sorrow, was too great affection for this present life. Nothing more hinders our joy in God, than the love of the world, and the sorrow of the world which comes from it.
