He that finds his life shall lose it: and he that loses his life for my sake shall find it.
All Commentaries on Matthew 10:39 Go To Matthew 10
John Chrysostom
AD 407
Do you see how great the damage to such as love it unduly? How great the gain to them that hate it? I mean, because the injunctions were disagreeable, when He was bidding them set themselves against parents, and children, and nature, and kindred, and the world, and their very soul, He sets forth the profit also, being very great. Thus, These things, says He, so far from harming, will very greatly profit; and their opposites will injure; urging them, as He ever does, by the very things which they desire. For why are you willing to despise your life? Because you love it? Then for that very reason despise it, and so you will advantage it in the highest degree, and do the part of one that loves it.
And mark an instance of unspeakable consideration. For not in respect of our parents only does He practise this reasoning, nor of our children, but with regard to our life, which is nearer than all; that the other point may thenceforth become unquestionable, and they may learn that they will in this way profit those of their kindred likewise, as much as may be; since so it is in the case even of our life, which is more essential to us than all.
