Ephesians 4:3

"Giving diligence," saith he, "to keep the unity of the Spirit in the bond of peace." Bind therefore thy hands with moderation. Again that goodly name of "bond." We had dismissed it, and it has of itself come back on us again. A goodly bond was that, and goodly is this one also, and that other is the fruit of this. Bind thyself to thy brother. They bear all things lightly who are bound together in love. Bind thyself to him and him to thee; thou art lord of both, for whomsoever I may be desirous to make my friend, I can by means of kindliness accomplish it. "Giving diligence," he says; a thing not to be done easily, and not in every one's power.

Let us then "follow after love;" he saith not simply let us love; but let us "follow after love." There is need of much eagerness: she is soon out of sight, she is most rapid in her flight; so many things are there in life which injure her. If we follow her, she will not outstrip us and get away, but we shall speedily recover her. The love of God is that which united earth to Heaven. It was the love of God that seated man upon the kingly throne. It was the love of God that manifested God upon earth. It was the love of God that made the Lord a servant. It was the love of God that caused the Beloved to be delivered up for His enemies, the Son for them that hated Him, the Lord for His servants, God for men, the free for slaves. Nor did it stop here, but called us to yet greater things. Yes, not only did it release us from our former evils, but promised, moreover, to bestow upon us other much greater blessings. For these things then let us give thanks to God, and follow after every virtue; and before all things, let us with all strictness practice love, that we may be counted worthy to attain the promised blessings; through the grace and loving-kindness of our Lord Jesus Christ, with whom, to the Father together with the Holy Ghost, be glory, might, and honor, now and for ever and ever. Amen.

So then, to return, there is no other reason for this, than that "love hath waxed cold;" and the cause again why love hath waxed cold, is that "iniquity abounds." For this leads to selfishness, and divides and severs the body, and relaxes it and rends it to pieces. But where virtue is, it does the reverse. Because the man that is virtuous is also above money; so that were there ten thousand such in poverty they would still be peaceable; whilst the covetous, where there are but two, can never be at peace. Thus then if we are virtuous, love will not perish, for virtue springs from love, and love from virtue. And how this is, I will tell you. The virtuous man does not value money above friendship, nor does he remember injuries, nor does wrong to his neighbor; he is not insolent, he endures all things nobly. Of these things love consists. Again, he who loves submits to all these things, and thus do they reciprocally produce one another. And this indeed, that love springs from virtue, appears from hence, because our Lord when He saith, "because iniquity shall be multiplied, the love of the many shall wax cold," plainly tells us this. And that virtue springs from love, Paul tells us, saying, "He that loveth his neighbor hath fulfilled the law." So then a man must be one of the two, either very affectionate and much beloved, or else very virtuous; for he who has the one, of necessity possesses the other; and, on the contrary, he who knows not how to love, will therefore commit many evil actions; and he who commits evil actions, knows not what it is to love.
