Who can say, I have made my heart clean; I am pure from my sin?
Purity of heart
I. Who can say, i have made my heart clean? We read of some who have clean hands, which implies an abstinence from outward sins. A clean heart implies more than this; it relates to the inward temper and disposition, to the bias of the will, and the various operations of the affections, as being spiritual and acceptable in the sight of God.
1. Purity of heart is much to be desired.
2. It is the work of the Spirit alone to impart it.
3. There is so much self-righteous pride and vanity in man that many are apt to think they have made their hearts clean.
II. Who can say, i am pure from my sin? To be pure from sin is similar to our being in a state of sinless perfection. This no one ever enjoyed in the present life, except Him only who “knew no sin.”
1. Who can say that they were never defiled with original sin, or that they are now free from that defilement?
2. Who can say that they are pure from inward sins, the evils of the heart?
3. Who can say that they are wholly free from practical evil in life and conversation?
4. Who can say they are free from every besetting sin, or that they are not defiled with any of those evils to which they are more especially exposed by constitutional habits, or by their occupation or immediate connections. As no one can say with truth that he is pure from his sin, what reason have the best of men to be abased before God! (B. Beddome, M. A.)
The duty of mortification
The trial and examination of our hearts and ways in reference to God is a duty which, though hard and difficult, is exceedingly useful and beneficial to us.
I. The duty of mortification. The cleansing of our hearts, to be pure from sin.
1. The nature of the action. Cleansing. A word implying some change and alteration that is to be made in us. That which is purged was formerly impure. God is pure; the saints are purged and purified. This shows us the nature of sin: it is a matter of uncleanness. Uncleanness is a debasing quality; a loathsome quality; a thing odious in itself and for itself. Cleansing shows the sovereign virtue of grace and repentance. It is of a purging virtue. It hath a power of cleansing us from the pollutions of sin. It is compared to clean water, which washes away filth. To a wind, which, passing, cleanseth. To a fire, that consumes dross and corruption.
2. The property of the agent. The text makes us agents in this great work. Sin is cleansed in our justification, when it is pardoned and forgiven. The act of forgiveness is God’s alone. Sin is cleansed by mortification, and regeneration, and conversion. The progress of these acts God works in us, and by us. His Spirit enables us to carry forward this work which He graciously begins, and to cleanse ourselves.
3. The circumstance of time. “I have cleansed.” Mortification is a work of long continuance; it requires progress and perseverance.
II. The object that must be wrought upon. “The heart.” The whole man must be cleansed, but first and specially the heart. The heart is the fountain and original from whence all other uncleannesses do stream and flow. The heart is the lurking-hole, to which sin betakes itself. The heart is the proper seat and residence of sin.
III. The measure or degree of mortification. “I am pure from my sin.” This is the high aim that a Christian must set to himself, to press forward to perfection. The text lays our sin at our own doors, and so it concerns us to rid ourselves of it. Sin is the offspring of our will. There is the sin of inbred and natural inclination; the sin to which our particular age disposes us: childhood is idle, youth wanton, age covetous; the sins of our calling and vocation: every calling has its special temptations.
IV. The difficulty of mortification. This question, “Who?” is not meant for all sorts of sinners. It is not propounded to the profane man, to the grossly ignorant man, or to the negligent and careless man. The question reaches to the best sort of men, those that have made good progress in this work of cleansing and mortification, who, nevertheless, are condemned by their own consciences; who have still leaven to purge out; find some sins of surreption will steal in upon them. As to the question itself. It runs thus: “Who can say?” Not “Who doth say?” or “Who will say?” or “Who dare say?” We may safely resolve the question into a peremptory assertion, and conclude that no man is clear or free from sin. The earnest Christian can say, “Through grace I have broken the strength and dominion of sin.” (Bp. Brownrigg.)
