28 For the Lord is a lover of righteousness, and takes care of his saints; they will be kept safe for ever; but the seed of the evil-doers will be cut off. 29 The upright will have the earth for their heritage, and will go on living there for ever. 30 The mouth of the good man says words of wisdom; the talk of his tongue is of righteousness. 31 The law of his God is in his heart; he will never make a false step. 32 The sinners are watching the upright man, desiring to put him to death. 33 The Lord will not give him into their hands, or be against him when he is judged.

34 Be waiting for the Lord, and keep his way; and you will be lifted up, and have the land for your heritage: when the evil-doers are cut off, you will see it. 35 I have seen the evil-doer in great power, covering the earth like a great tree. 36 But he came to an end, and there was no sign of him; I made a search for him and he was not there. 37 Give attention to the good man, and take note of the upright; because the end of that man is peace. 38 But as for the sinners, they will be cut off together; the end of the wrongdoers is destruction.

Commentary on Psalm 37:21-33

(Read Psalm 37:21-33)

The Lord our God requires that we do justly, and render to all their due. It is a great sin for those that are able, to deny the payment of just debts; it is a great misery not to be able to pay them. He that is truly merciful, will be ever merciful. We must leave our sins; learn to do well, and cleave to it. This is true religion. The blessing of God is the spring, sweetness, and security of all earthly enjoyments. And if we are sure of this, we are sure not to want any thing good for us in this world. By his grace and Holy Spirit, he directs the thoughts, affections, and designs of good men. By his providence he overrules events, so as to make their way plain. He does not always show them his way for a distance, but leads them step by step, as children are led. God will keep them from being ruined by their falls, either into sin or into trouble, though such as fall into sin will be sorely hurt. Few, if any, have known the consistent believer, or his children, reduced to abject, friendless want. God forsakes not his saints in affliction; and in heaven only the righteous shall dwell for ever; that will be their everlasting habitation. A good man may fall into the hands of a messenger of Satan, and be sorely buffeted, but God will not leave him in his enemy's hands.

Commentary on Psalm 37:34-40

(Read Psalm 37:34-40)

Duty is ours, and we must mind it; but events are God's, we must refer the disposal of them to him. What a striking picture is in verses 35,36, of many a prosperous enemy of God! But God remarkably blights the projects of the prosperous wicked, especially persecutors. None are perfect in themselves, but believers are so in Christ Jesus. If all the saint's days continue dark and cloudy, his dying day may prove comfortable, and his sun set bright; or, if it should set under a cloud, yet his future state will be everlasting peace. The salvation of the righteous will be the Lord's doing. He will help them to do their duties, to bear their burdens; help them to bear their troubles well, and get good by them, and, in due time, will deliver them out of their troubles. Let sinners then depart from evil, and do good; repent of and forsake sin, and trust in the mercy of God through Jesus Christ. Let them take his yoke upon them, and learn of him, that they may dwell for evermore in heaven. Let us mark the closing scenes of different characters, and always depend on God's mercy.
