2 Which things must all now be considered by us, that no one may desire anything from the world that is now dying, but may follow Christ, who both lives for ever, and quickens His servants, who are established in the faith of His name. For there comes the time, beloved brethren, which our Lord long ago foretold and taught us was approaching, saying, “The time comes, that whosoever kills you will think that he does God service. And these things they will do unto you, because they have not known the Father nor me.
But these things have I told you, that when the time shall come, you may remember that I told you of them.” Nor let any one wonder that we are harassed with constant persecutions, and continually tried with increasing afflictions, when the Lord before predicted that these things would happen in the last times, and has instructed us for the warfare by the teaching and exhortation of His words. Peter also, His apostle, has taught that persecutions occur for the sake of our being proved, and that we also should, by the example of righteous men who have gone before us, be joined to the love of God by death and sufferings.
For he wrote in his epistle, and said, “Beloved, think it not strange concerning the fiery trial which is thing happened unto you; but as often as you partake in Christ's sufferings, rejoice in all things, that when His glory shall be revealed, you may be glad also with exceeding joy. If you are reproached in the name of Christ, happy are you; for the name of the majesty and power of the Lord rests on you, which indeed on their part is blasphemed, but on our part is glorified.”
Now the apostles taught us those things which they themselves also learnt from the Lord's precepts and the heavenly commands, the Lord Himself thus strengthening us, and saying, “There is no man that has left house, or land, or parents, or brethren, or sisters, or wife, or children, for the kingdom of God's sake, who shall not receive sevenfold more in this present time, and in the world to come life everlasting.” And again He says, “Blessed are you when men shall hate you, and shall separate you from their company, and shall cast you out, and shall reproach your name as evil for the Son of man's sake. Rejoice in that day, and leap for joy; for, behold your reward is great in heaven.”1
