These things I have spoken unto you, that in me you might have peace. In the world you shall have tribulation: but be of good cheer; I have overcome the world.

Cyril of Alexandria
AD 444
Christ herein, so to say, well sums up to our profit His discourse to them; and, compressing into a few words the meaning of what He had said, sets before them in brief the knowledge of His Will. For I have now, He says, spoken these words unto you, exhorting you to have peace in Me, and that ye may also know clearly that you will meet with trouble in the world, and will be involved in many tribulations for My sake. But you will not be vanquished by the perils that encompass you, for I have overcome the world.
But that I may make what I have said as clear as possible unto you, come let me first explain what "having peace in Christ" means. For the world, or those who are enamoured of the things in the world, are continually at peace among themselves, but in nowise have they peace in Christ. As, for example, the dissolute seekers of the pleasures of sense are therefore most dear and acceptable to those of similar pursuits; and the man who covets riches that do not belong to him, and is for this reason grasping or thievish, will be altogether to the taste of those who practise a kindred vice. For every creature loves his kind, according to the saying, and man will be attracted to his like. But in all connexions of this sort the holy name of peace is put to base uses; and the proverb is true, but it is not with the Saints as it is with the wicked. For sin is not the bond of peace, but faith, hope, love, and the power of piety towards God. And this is in Christ. The chiefest then of all good gifts towards us is clearly peace in Christ, which brings in its train brotherly love as near akin to itself. Paul says that love is the perfect fulfilling of the Divine Law; and that to those who love one another will surely come the love of God Himself above all things else is beyond question, as John says that if a man love his brother he will as a consequence love God Himself.
He points out also another truth, I mean in the words: In the world ye have tribulation: but be of good cheer; I have overcome the world. Any one choosing to construe these words in a simple sense might reason thus: Christ appeared superior to, and stronger than, every sin and worldly hindrance; and since He has conquered, He will also bestow the power to conquer upon such as attempt the struggle for His sake. And if any man seek to find a more recondite meaning for the words, he might reflect in this wise: Just as we have hereby overcome corruption and death, since as Man, for us and for our sakes Christ became alive again, making His own Resurrection the beginning of the conquest over death, the power of His Resurrection will surely extend even unto us, since He that overcame death was one of us, insomuch as He was Incarnate Man; and as we overcome sin, and as we overcome death that wholly died in Christ first, Christ, that is, being the purveyor to us of the blessing as His own kindred, so also we ought to be of good cheer, because we shall overcome the world; for Christ as Man overcame it for our sakes, being herein the Beginning and the Gate and the Way for the race of man. For they who once were fallen and vanquished have now overcome and are conquerors, through Him Who conquered as one of ourselves, and for our sakes. For if He conquered as God, then it profiteth us nothing; but if as man, we are herein conquerors. For He is to us the Second Adam come from heaven, according to the Scripture. Just as then we have borne the image of the earthy, according to its likeness falling under the yoke of sin, so likewise also shall we bear the image of the heavenly, that is Christ, overcoming the power of sin and triumphing over all the tribulation of the world; for Christ has overcome the world.
