Psalms 19:13

God's word warns the wicked not to go on in his wicked way, and warns the righteous not to turn from his good way. There is a reward, not only after keeping, but in keeping God's commandments. Religion makes our comforts sweet, and our crosses easy, life truly valuable, and death itself truly desirable. David not only desired to be pardoned and cleansed from the sins he had discovered and confessed, but from those he had forgotten or overlooked. All discoveries of sin made to us by the law, should drive us to the throne of grace, there to pray. His dependence was the same with that of every Christian who says, Surely in the Lord Jesus have I righteousness and strength. No prayer can be acceptable before God which is not offered in the strength of our Redeemer or Divine Kinsman, through Him who took our nature upon him, that he might redeem us unto God, and restore the long-lost inheritance. May our hearts be much affected with the excellence of the word of God; and much affected with the evil of sin, and the danger we are in of it, and the danger we are in by it.

"Keep back thy servant also from presumptuous sins; let them not have dominion over me." This earnest and humble prayer teaches us that saints may fall into the worst of sins unless restrained by grace, and that therefore they must watch and pray lest they enter into temptation. There is a natural proneness to sin in the best of men, and they must be held back as a horse is held back by the bit or they will run into it. Presumptuous sins are peculiarly dangerous. All sins are great sins, but yet some sins are greater than others. Every sin has in it the very venom of rebellion, and is full of the essential marrow of traitorous rejection of God; but there be some sins which have in them a greater development of the essential mischief of rebellion, and which wear upon their faces more of the brazen pride which defies the Most High. It is wrong to suppose that because all sins will condemn us, that therefore one sin is not greater than another. The fact is, that while all transgression is a greatly grievous and sinful thing, yet there are some transgressions which have a deeper shade of blackness, and a more double scarlet-dyed hue of criminality than others. The presumptuous sins of our text are the chief and worst of all sins; they rank head and foremost in the list of iniquities. It is remarkable that though an atonement was provided under the Jewish law for every kind of sin, there was this one exception: "But the soul that sinneth presumptuously shall have no atonement; it shall be cut off from the midst of the people." And now under the Christian dispensation, although in the sacrifice of our blessed Lord there is a great and precious atonement for presumptuous sins, whereby sinners who have erred in this manner are made clean, yet without doubt, presumptuous sinners, dying without pardon, must expect to receive a double portion of the wrath of God, and a more terrible portion of eternal punishment in the pit that is digged for the wicked. For this reason is David so anxious that he may never come under the reigning power of these giant evils. "Then shall I be upright, and I shall be innocent from the great transgression." He shudders at the thought of the unpardonable sin. Secret sin is a stepping-stone to presumptuous sin, and that is the vestibule of "the sin which is unto death." He who is not wilful in his sin, will be in a fair way to be innocent so far as poor sinful man can be; but he who tempts the devil to tempt him is in a path which will lead him from bad to worse, and from the worse to the worst.
