Most lament psalms have the following typical features: invocation, complaint, request, expression of confidence, and vow of praise.
Surely we too may stop awhile, and meditate upon the deep-seated folly of the wicked, their continuance in evil, and their sure destruction; and we may learn to admire that grace which has made us to differ, and taught us to love truth, and seek after righteousness.
Observe, that David speaks first to God and then to men. Surely we should all speak the more boldly to men if we had more constant converse with God. He who dares to face his Maker will not tremble before the sons of men.
When the Jew offered sacrifice righteously, that is, in a spiritual manner, he thereby set forth the Redeemer, the great sin-atoning Lamb; there is, therefore, the full gospel in this exhortation of the Psalmist. O sinners, flee ye to the sacrifice of Calvary, and there put your whole confidence and trust, for he who died for men is the LORD JEHOVAH.
As for worldlings, this is their unceasing cry. "Who will shew us any good?" Never satisfied, their gaping mouths are turned in every direction, their empty hearts are ready to drink in any fine delusion which impostors may invent; and when these fail, they soon yield to despair, and declare that there is no good thing in either heaven or earth.
Behold, Lord, an empty vessel that needs to be filled. My Lord, fill it. I am weak in the faith; strengthen me. I am cold in love; warm me and make me fervent that my love may go out to my neighbor. I do not have a strong and firm faith; at times I doubt and am unable to trust You altogether. O Lord, help me. Strengthen my faith and trust in You. In You I have sealed the treasures of all I have. I am poor; You are rich and have been merciful to the poor. I am a sinner; You are upright. With me there is an abundance of sin; in You is the fullness of righteousness. Therefore, I will remain with You of whom I can receive but to whom I may not give. Amen.
