Your justice;[1] in the common Greek copies, your alms, which seems to be the sense in this place. (Witham) — Hereby it is plain that good works are justice, and that man doing them doth justice, and is thereby just and justified, and not by faith only. All which justice of a christian man, our Saviour here compriseth in the three eminent good works, alms deeds, prayer, and fasting. (St. Augustine, lib. perf. just. chap. viii.) So that to give alms is to do justice, and the works of mercy are justice. (St. Augustine, in Psalm xlix, ver. 5.) (Bristow) — St. Gregory says, that the man who by his virtuous actions would gain the applause of men, quits at an easy rate a treasure of immense value; for, with what he might purchase the kingdom of heaven, he only seeks to acquire the transitory applause of mortals. This precept of Christ, says St. Chrysostom, beautifully evinces the solicitude and unspeakable goodness of God, lest we should have the labour of performing good works, and on account of evil motives be deprived of our reward. (Hom. xix.) “Shut up alms in the heart of the poor.” (Ecclesiasticus xxix. 15.)
Ambition maketh alms vain. This word, Reward, is always taken in the Scriptures for a free recompense, and therefore the schoolmen do fondly set it to be answerable to a deserving, which they call merit.
Christ having, in the former chapter, armed his disciples against the corrupt doctrines and opinions of the scribes and Pharisees, especially in their expositions of the law (that was called their leaven, ch. 16 12), comes in this chapter to warn them against their corrupt practices, against the two sins which, though in their doctrine they did not justify, yet in their conversation they were notoriously guilty of, and so as even to recommend them to their admirers: these were hypocrisy and worldly-mindedness, sins which, of all others, the professors of religion need most to guard against, as sins that most easily beset those who have escaped the grosser pollutions that are in the world through lust, and which are therefore highly dangerous. We are here cautioned, I. Against hypocrisy; we must not be as the hypocrites are, nor do as the hypocrites do. 1. In the giving of alms, ver 1-4. 2. In prayer, ver 5-8. We are here taught what to pray for, and how to pray (ver 9-13); and to forgive in prayer, ver 14, 15. 3. In fasting, ver 16-18. II. Against worldly-mindedness, 1. In our choice, which is the destroying sin of hypocrites, ver 19-24. 2. In our cares, which is the disquieting sin of many good Christians, ver 25-34.
Mat 6:1-4 Christ continuing his sermon, giveth directions about alms giving, Mat 6:5-13 prayer, Mat 6:14-15 forgiving our brethren, Mat 6:16-18 fasting, Mat 6:19-21 laying up treasure in heaven, Mat 6:22-23 keeping a single eye, Mat 6:24-31 and exhorteth not to be anxious about worldly things, but principally to seek God’s kingdom and righteousness.
Verses 1-4 Our Lord next warned against hypocrisy and outward show in religious duties. What we do, must be done from an inward principle, that we may be approved of God, not that we may be praised of men. In these verses we are cautioned against hypocrisy in giving alms. Take heed of it. It is a subtle sin; and vain-glory creeps into what we do, before we are aware. But the duty is not the less necessary and excellent for being abused by hypocrites to serve their pride. The doom Christ passes, at first may seem a promise, but it is their reward; not the reward God promises to those who do good, but the reward hypocrites promise themselves, and a poor reward it is; they did it to be seen of men, and they are seen of men. When we take least notice of our good deeds ourselves, God takes most notice of them. He will reward thee; not as a master who gives his servant what he earns, and no more, but as a Father who gives abundantly to his son that serves him.
This must be understood figuratively, that we must avoid all ostentation in the performance of our good works. Many respectable authors are of opinion, that it was customary with the Pharisees and other hypocrites, to assemble the poor they designed to relieve by sound of trumpet. (Menochius) — Let us avoid vain glory, the agreeable plunderer of our good works, the pleasant enemy of our souls, which presents its poison to us under the appearance of honey. (St. Basil)
1 Take heed that ye do not your alms before men, to be seen of them: otherwise ye have no reward of your Father which is in heaven. 2 Therefore when thou doest thine alms, do not sound a trumpet before thee, as the hypocrites do in the synagogues and in the streets, that they may have glory of men. Verily I say unto you, They have their reward. 3 But when thou doest alms, let not thy left hand know what thy right hand doeth: 4 That thine alms may be in secret: and thy Father which seeth in secret himself shall reward thee openly.
As we must do better than the scribes and Pharisees in avoiding heart-sins, heart-adultery, and heart-murder, so likewise in maintaining and keeping up heart-religion, doing what we do from an inward, vital principle, that we may be approved of God, not that we may be applauded of men; that is, we must watch against hypocrisy, which was the leaven of the Pharisees, as well as against their doctrine, Luke xii. 1. Almsgiving, prayer, and fasting, are three great Christian duties—the three foundations of the law, say the Arabians: by them we do homage and service to God with our three principal interests; by prayer with our souls, by fasting with our bodies, by alms-giving with our estates. Thus we must not only depart from evil, but do good, and do it well, and so dwell for evermore.
