Rejoice with them ... - This command grows out of the doctrine stated in Romans 12:4-5, that the church is one; that it has one interest; and therefore that there should be common sympathy in its joys and sorrows. Or, enter into the welfare of your fellow-Christians, and show your attachment to them by rejoicing that they are made happy; compare 1 Corinthians 12:26, "And whether .... one member be honored, all the members rejoice with it." In this way happiness diffuses and multiplies itself. It becomes expanded over the face of the whole society; and the union of the Christian body tends to enlarge the sphere of happiness and to prolong the joy conferred by religion. God has bound the family of man together by these sympathies, and it is one of the happiest of all devices to perpetuate and extend human enjoyments.

Weep ... - See the note at John 11:35. At the grave of Lazarus our Saviour evinced this in a most tender and affecting manner. The design of this direction is to produce mutual kindness and affection, and to divide our sorrows by the sympathies of friends. Nothing is so well suited to do this as the sympathy of those we love. All who are afflicted know how much it diminishes their sorrow to see others sympathizing with them, and especially those who evince in their sympathies the Christian spirit. How sad would be a suffering world if there were none who regarded our griefs with interest or with tears! if every sufferer were left to bear his sorrows unpitied and alone! and if all the ties of human sympathy were rudely cut at once, and people were left to suffer in solitude and unbefriended! It may be added that it is the special duty of Christians to sympathize in each other's griefs:

(1) Because their Saviour set them the example;

(2) Because they belong to the same family;

(3) Because they are subject to similar trials and afflictions; and,

(4) Because they cannot expect the sympathy of a cold and unfeeling world.

Rejoice with them that do rejoice - Take a lively interest in the prosperity of others. Let it be a matter of rejoicing to you when you hear of the health, prosperity, or happiness of any brother.

Weep with them that weep - Labour after a compassionate or sympathizing mind. Let your heart feel for the distressed; enter into their sorrows, and bear a part of their burdens. It is a fact, attested by universal experience, that by sympathy a man may receive into his own affectionate feelings a measure of the distress of his friend, and that his friend does find himself relieved in the same proportion as the other has entered into his griefs. "But how do you account for this?" I do not account for it at all, it depends upon certain laws of nature, the principles of which have not been as yet duly developed.

Rejoice with them that do rejoice,.... Not in anything sinful and criminal, in a thing of nought, in men's own boastings; all such rejoicing is evil, and not to be joined in; but in things good and laudable, as in outward prosperity; and to rejoice with such, is a very difficult task; for unless persons have a near concern in the prosperity of others, they are very apt to envy it, or to murmur and repine, that they are not in equal, or superior circumstances; and also in things spiritual, with such who rejoice in the discoveries of God's love to their souls, in the views of interest in Christ, and of peace, pardon, and righteousness by him, and in hope of the glory of God; when such souls make their boast in the Lord, the humble hearing thereof will be glad, and will, as they ought to do, join with them in magnifying the Lord, and will exalt his name together:

and weep with them that weep; so Christ, as he rejoiced with them that rejoiced, at the marriage in Cana of Galilee, wept with them that wept, with Mary at the grave of Lazarus. The design of these rules is to excite and encourage sympathy in the saints with each other, in all conditions inward and outward, and with respect to things temporal and spiritual; in imitation of Christ their great high priest, who cannot but be touched with the infirmities of his people; and as founded upon, and arising from, their relation to each other, as members of the same body; see 1 Corinthians 12:26;

Rejoice with them that do rejoice, and weep with them that weep.

12:15 Rejoice with them that do rejoice, etc. Sympathize with the joys and sorrows of others.

12:15 Rejoice - The direct opposite to weeping is laughter; but this does not so well suit a Christian.

15. Rejoice with them that rejoice; and weep-the "and" should probably be omitted.

with them that weep-What a beautiful spirit of sympathy with the joys and sorrows of others is here inculcated! But it is only one charming phase of the unselfish character which belongs to all living Christianity. What a world will ours be when this shall become its reigning spirit! Of the two, however, it is more easy to sympathize with another's sorrows than his joys, because in the one case he needs us; in the other not. But just for this reason the latter is the more disinterested, and so the nobler.

12:9-16 The professed love of Christians to each other should be sincere, free from deceit, and unmeaning and deceitful compliments. Depending on Divine grace, they must detest and dread all evil, and love and delight in whatever is kind and useful. We must not only do that which is good, but we must cleave to it. All our duty towards one another is summed up in one word, love. This denotes the love of parents to their children; which is more tender and natural than any other; unforced, unconstrained. And love to God and man, with zeal for the gospel, will make the wise Christian diligent in all his wordly business, and in gaining superior skill. God must be served with the spirit, under the influences of the Holy Spirit. He is honoured by our hope and trust in him, especially when we rejoice in that hope. He is served, not only by working for him, but by sitting still quietly, when he calls us to suffer. Patience for God's sake, is true piety. Those that rejoice in hope, are likely to be patient in tribulation. We should not be cold in the duty of prayer, nor soon weary of it. Not only must there be kindness to friends and brethren, but Christians must not harbour anger against enemies. It is but mock love, which rests in words of kindness, while our brethren need real supplies, and it is in our power to furnish them. Be ready to entertain those who do good: as there is occasion, we must welcome strangers. Bless, and curse not. It means thorough good will; not, bless them when at prayer, and curse them at other times; but bless them always, and curse not at all. True Christian love will make us take part in the sorrows and joys of each other. Labour as much as you can to agree in the same spiritual truths; and when you come short of that, yet agree in affection. Look upon worldly pomp and dignity with holy contempt. Do not mind it; be not in love with it. Be reconciled to the place God in his providence puts you in, whatever it be. Nothing is below us, but sin. We shall never find in our hearts to condescend to others, while we indulge conceit of ourselves; therefore that must be mortified.
