“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” (John 15:19).
A Christian will be persecuted. We have to be prepared for this and not be surprised when it happens. Christ prepared us for this. Our faith in him makes us different from the world if we do his will and live for him with all our heart, as he wishes. The world lives for itself and its pleasures. A Christian mortifies and sacrifices himself for the love of Christ so that all his love goes directly to him. He detaches himself for the sake of Christ to love him with all his heart. Therefore he renounces the pleasures of this world and lives a mortified, ascetical life, a life of sacrifice and love of God. He renounces the world and its delights, delicacies, and pleasures in every aspect of his life, from his diet and way of dressing to how he spends his free time. He renounces the diversions and entertainments of this world in order to love God with all his heart, not with a heart divided and dissipated by the pleasures of the world. Thus he lives only for God, only for Christ, and his life is very different from the life of the world, from a worldly life.
Therefore the world does not love him. It neither understands nor accepts him. The world rejects and persecutes him. But he continues living this way, only for God with all his heart, with a radically undivided heart, and he continues preaching the gospel.
As Christ was rejected and persecuted by the world, in the same way the Christian will also be rejected and persecuted by the world. But he knows this. It does not surprise him. It is what he expects, for Christ prepared him for this. He told us, “You will be hated by all for my name’s sake. But he who endures to the end will be saved. When they persecute you in one town, flee to the next” (Matt. 10:22-23). So we continue with our way of life and our ministry in another place, as did St. Paul, who was imprisoned, stoned, beaten, and driven out of one city after another. Again and again he departed from where they persecuted him and went to another town and preached Christ there. We should do the same, not daunted by past rejections and persecution.
“Do not wonder, brethren, that the world hates you” (1 John 3:13). “Indeed all who desire to live a godly life in Christ Jesus will be persecuted” (2 Tim. 3:12). “If they have called the master of the house Beelzebul, how much more will they malign those of his household” (Matt. 10:25). “The world has hated them because they are not of the world, even as I am not of the world” (John 17:14). “If they persecuted me, they will persecute you” (John 15:20).
This will be our life if we want to be Christians. It is a life of the cross. As they persecuted Jesus, so will they persecute us if we follow him with all our heart, renouncing the way of living of the world in its worldliness in order to live for Christ with all our heart.
