Verse 1-5 — None of our sins or sufferings should prevent our ascribing glory and praise to the Lord. The more unworthy we are, the more is his kindness to be admired. And those who depend on the Redeemer's righteousness will endeavour to copy his example, and by word and deed to show forth his praise. God's people have reason to be cheerful people; and need not envy the children of men their pleasure or pride.
Verse 6-12 — Here begins a confession of sin; for we must acknowledge that the Lord has done right, and we have done wickedly. We are encouraged to hope that though justly corrected, yet we shall not be utterly forsaken. God's afflicted people own themselves guilty before him. God is distrusted because his favours are not remembered. If he did not save us for his own name's sake, and to the praise of his power and grace, we should all perish.
Verse 13-33 — Those that will not wait for God's counsel, shall justly be given up to their own hearts' lusts, to walk in their own counsels. An undue desire, even for lawful things, becomes sinful. God showed his displeasure for this. He filled them with uneasiness of mind, terror of conscience, and self-reproach. Many that fare deliciously every day, and whose bodies are healthful, have leanness in their souls: no love to God, no thankfulness, no appetite for the Bread of life, and then the soul must be lean. Those wretchedly forget themselves, that feast their bodies and starve their souls. Even the true believer will see abundant cause to say, It is of the Lord's mercies that I am not consumed. Often have we set up idols in our hearts, cleaved to some forbidden object; so that if a greater than Moses had not stood to turn away the anger of the Lord, we should have been destroyed. If God dealt severely with Moses for unadvised words, what do those deserve who speak many proud and wicked words? It is just in God to remove those relations that are blessings to us, when we are peevish and provoking to them, and grieve their spirits.
Verse 34-48 — The conduct of the Israelites in Canaan, and God's dealings with them, show that the way of sin is down-hill; omissions make way for commissions: when they neglected to destroy the heathen, they learned their works. One sin led to many more, and brought the judgments of God on them. Their sin was, in part, their own punishment. Sinners often see themselves ruined by those who led them into evil. Satan, who is a tempter, will be a tormentor. At length, God showed pity to his people for his covenant's sake. The unchangeableness of God's merciful nature and love to his people, makes him change the course of justice into mercy; and no other change is meant by God's repentance. Our case is awful when the outward church is considered. When nations professing Christianity, are so guilty as we are, no wonder if the Lord brings them low for their sins. Unless there is general and deep repentance, there can be no prospect but of increasing calamities. The psalm concludes with prayer for completing the deliverance of God's people, and praise for the beginning and progress of it. May all the people of the earth, ere long, add their Amen.
