1 John 3:18
My little children, let us not love in word, neither in tongue, but in deed and in truth.
The apostle, first of all, makes a general application of the thought which was included in the last sentence: And do not wonder, brethren, if the world hates you. What the righteous Abel experienced in the first days of the world's history is the lot of all the righteous since his time. So it must not be a matter of surprise to us if we incur the hatred and must bear the enmity of the children of the world. John 15:18; John 17:14; Matthew 10:16. Although the Christians are offering to the unbelievers the most wonderful blessings which were ever brought to this earth, although their one aim is to do good to all men, yet the unregenerate persistently resent the refusal of the Christians to join them in their transgressions. But this is not to be marveled at, because we are dealing with the world, with the children of unbelief, with such as willingly become identified with the trespass of Cain. Because the unbelievers prefer their life of sin and unbelief, which will finally land them in everlasting destruction, they cannot but hate the Christians.
The contrast, therefore, will remain: On our part, we know that we have passed out of death into life, because we love the brethren; he that does not love his brother remains in death. The distinction between unbelievers and believers, between world and Church, is clear and will remain till the end of time. So far as we are concerned, we have the knowledge, we are sure, that we have left our former state of spiritual death and have passed over to the true life in and with God. Our hearts that were formerly dead in sins are now turned to God in faith and love. We know that we have forgiveness of sins, and thus we have the willingness and the power to do that which pleases God. It was not a case of our choosing to embrace the truth, but of God's choosing us and drawing us to Himself in the fullness of His mercy and grace. Of this we have evidence in the fact that we love the brethren. If we had not been converted through the power of God, it would be impossible for us to love the brethren. Noun-regenerated person is able to feel and to give evidence of real, genuine love. But the absence of this love is a sure sign that such a person is still lying in the death of sins. Moreover, he will remain in this spiritual death as long as he continues in his uncharitable attitude. In a case of this kind all external worship, all pretense at prayer, all churchgoing, all conversing of God and things divine, will avail nothing whatever: he that has no true love and gives no evidence of true love will remain in death until the Spirit of God works spiritual life in him.
The apostle repeats the same truth from the positive side: Every one that hates his brother is a murderer, and you know that no murderer has eternal life abiding in him. In the phraseology of St. John, "not to love" and "to hate" are evidently synonyms; there is no neutral ground. That is the condition of natural man after the Fall: he has no true love for his neighbor in his heart, but only hatred, since being indifferent in the sight of God is identical with hating. Natural man is selfish and loves only himself. And therefore he is, in the judgment of God, a murderer, a homicide; for God judges the disposition of the heart. This is one of the strongest passages in Scriptures to throw the responsibility, also for sins of desire, of the heart, on the sinner. And all such men, all that are guilty of hatred, of the lack of proper love for their brother, have not the eternal life, that spiritual life which is begun in conversion and lasts beyond the grave, abiding in them. They belong in the kingdom of the devil, the murderer from the beginning. That is the terrible, the fearful lot of those that do not love their brethren. What an earnest warning to Christians not to let the love for their brethren leave their hearts, since the new spiritual life cannot remain in their hearts under such circumstances!
The apostle now gives a description and example of genuine brotherly love: In this have we known love, that He has laid down His life for us; and we should lay down our lives for the brethren. This is the one perfect example and type of love for all times. We Christians have realized and know what love is and means, wherein true love consists, how it expresses itself, in the example of Christ. For He, out of free love and merciful favor, laid down His life for us; He suffered the death which we had earned by our sins. His own holy life He laid down as the ransom, as the price, thus giving up the greatest, the most precious of earth's gifts in order to deliver us. As one that was cursed of God, as a criminal in the sight of men He gave up His life. This example of love, than which there can be none more perfect, we Christians have before our eyes always. It teaches us the great lesson and obligation to love our brethren to such a degree as also to be willing to lay down our lives for them, if it will be for their benefit, to their advantage. Naturally this greatest sacrifice includes all the smaller services which we are called upon to perform for the brethren, the Christians ever forgetting, denying themselves in order to help and be of service to others.
Diametrically opposed to such unselfishness is the conduct which the apostle describes: But whoever has a living in this world and sees his brother have need and shuts up his mercies from him, how does the love of God remain in him? If we are under obligations to give up the highest and most precious gift of life for the sake of our brother, the smaller sacrifices, the minor evidences of love, will certainly offer no difficulties. If a person has a comfortable living in this world, if he possesses enough of this world's goods for his own support and that of his family, those dependent upon him, he should really have incentive enough to share willingly with those in need. If such a one, however, sees his brother, his neighbor, in want, lacking the actual necessities of life, if he becomes a witness of his sorry plight, and yet closes up his heart before him, turns from him in the hardness of his heart, surely the conclusion is justified that he has lost the love and the faith which he might have possessed at one time. In such a case the Lord will also turn from him, will withdraw His love from the heartless wretch, since the love which the Lord demanded of him is no longer in evidence in his conduct and life. He has fallen back into spiritual death.
St. John, therefore, admonishes: Little children, let us not love with word or with the tongue, but in deed and in truth. Talk is cheap, as St. James shows, chap. 2:15-16, but it does not provide warm clothing or nourishing food. The mere expression of good will, unless backed up by real deeds, by acts which will provide the assistance for which the need is shown to exist, is worthless, a hollow sound. In some cases, indeed, it may be forgetfulness on the part of the Christians when they fail to provide for needs which are shown to exist, but in others there is danger of damnable hypocrisy, that covetousness and love of money hinder the professed Christian from showing concrete proof of the brotherly love of which he should give evidence. This admonition is certainly timely in these latter days of the dying out of true love, Matthew 24:12.
