Romans 14:19

Let us therefore follow after the things,
Since the kingdom of God is in part peace, and the man that serves Christ in this, as in other things, is accepted with God, and grateful to men, the apostle very pertinently exhorts to seek after such things,

which make for peace:
not with God, for, for a sinful creature to make peace with God is impracticable and impossible, nor is there any exhortation to it in all the word of God; and if there was, it would be unnecessary here; since the persons here exhorted were such for whom peace with God was made by Christ, and who had a clear and comfortable sense of it in their own souls; and besides, for any to be put upon, or to attempt to make their peace with God, must highly reflect upon the methods of God's grace, in reconciling sinners to himself; and be injurious to the blood, sacrifice, and satisfaction of Christ, by which only peace is made: but the apostle means, either what makes for a man's own peace, or for the peace of others; the things which make for a man's own peace in his own conscience distressed with sin, are looking to, and dealing with the blood of Christ, which speaks peace and pardon; and the righteousness of Christ, which being apprehended by faith, a soul has peace with God through Christ; and also an embracing the Gospel, and the truths of it, which direct to Christ, which publish peace, and are the means of increasing and establishing a solid and well grounded peace, on the free grace of God and merits of Christ: attending on ordinances, and exercising a conscience void of offence towards God and men, are means of continuing and promoting a man's peace; he enjoys peace in them, though he do not derive it from them; yea, in the peace of others, is a man's own peace; and this is what is chiefly meant, a pursuing of things which make for the peace of others; of all men, and especially of saints; this is what should be eagerly followed after, closely pursued, and all ways and means should be made use of, to promote and secure it: this is the will of God; it is well pleasing to Christ, and a fruit of the Spirit; it is one part of the Gospel dispensation; church fellowship cannot be profitable and pleasant without it; it suits with the character of saints, who are sons of peace; and agrees with their privileges they enjoy, or have a right unto, as spiritual peace here, and eternal peace hereafter;

and things wherewith one may edify another.
The church is often compared to a building, to a temple, a city, an house, and saints are the materials thereof; who are capable of being edified, or built up, yet more and more, both by words and by deeds; by words, by the ministry of the word, which is set up and continued among other things, for the edifying of the body of Christ; by praying with, and for each other; and by Christian conversation, about the experience of the grace of God, and doctrines of the Gospel, whereby saints may be useful in building up one another in their most holy faith; and so likewise by avoiding all filthy, frothy, and corrupt communication; all angry words and wrathful expressions, which tend not to profit, and are not for the use of edifying, but the contrary: moreover, edification is promoted by deeds, by acts of charity, or love; for charity edifies not by bare words but by loving in deed and in truth, by serving one another in love; for the spiritual body of Christ his church, makes increase unto the edifying of itself in love; and also by laying aside the use of things indifferent, when disagreeable to any of the brethren; for though all things may be lawful to be done by us, yet all things do not edify the brethren; and things which make for the edification of the body, as well as our own, are diligently to be sought after. The Vulgate Latin version, and some copies, read, "let us keep", or "observe those things wherewith one may edify another".
