Mt 7:12 ¶ Therefore all things whatsoever ye would that men should do to you, do ye even so to them: for this is the law and the prophets.13 Enter ye in at the strait gate: for wide is the gate, and broad is the way, that leadeth to destruction, and many there be which go in thereat:14 Because strait is the gate, and narrow is the way, which leadeth unto life, and few there be that find it.
The rule of justice laid down; Whatsoever ye would that men should do to you, do you even so to them. Jesus Christ came to teach us, not only what we are to know and believe, but what we are to do; what we are to do, not only toward God, but toward men; not only towards our fellow-disciples, those of our party and persuasion, but towards men in general, all with whom we have to do. The golden rule of equity is, to do to others as we would they should do to us. We must not do to others the evil they have done us, nor the evil which they would do to us, if it were in their power; nor may we do that which we think, if it were done to us, we could bear contentedly, but what we desire should be done to us. This is grounded upon that great commandment, Thou shalt love thy neighbor as thyself.
As we must bear the same affection to our neighbour that we would have borne to ourselves, so we must do the same good to others. The meaning of this rule lies in three things. (1.) We must do that to our neighbour which we ourselves acknowledge to be fit and reasonable: the appeal is made to our own judgment, and the discovery of our judgment is referred to that which is our own will and expectation, when it is our own case. (2.) We must put other people upon the level with ourselves, and reckon we are as much obliged to them, as they to us. We are as much bound to the duty of justice as they, and they as much entitled to the benefit of it as we. (3.) We must, in our dealings with men, suppose ourselves in the same particular case and circumstances with those we have to do with, and deal accordingly. If I were making such a one's bargain, labouring under such a one's infirmity and affliction, how should I desire and expect to be treated? And this is a just supposition, because we know not how soon their case may really be ours: at least we may fear, lest God by his judgments should do to us as we have done to others, if we have not done as we would be done by.
