Psalms 109:21

The psalmist takes God's comforts to himself, but in a very humble manner. He was troubled in mind. His body was wasted, and almost worn away. But it is better to have leanness in the body, while the soul prospers and is in health, than to have leanness in the soul, while the body is feasted. He was ridiculed and reproached by his enemies. But if God bless us, we need not care who curses us; for how can they curse whom God has not cursed; nay, whom he has blessed? He pleads God's glory, and the honour of his name. Save me, not according to my merit, for I pretend to none, but according to thy-mercy. He concludes with the joy of faith, in assurance that his present conflicts would end in triumphs. Let all that suffer according to the will of God, commit the keeping of their souls to him. Jesus, unjustly put to death, and now risen again, is an Advocate and Intercessor for his people, ever ready to appear on their behalf against a corrupt world, and the great accuser.

But do thou for me, O God the Lord, for thy name's sake. How eagerly he turns from his enemies to his God! He sets the great THOU in opposition to all his adversaries, and you see at once that his heart is at rest. The words are very indistinct and though our version may not precisely translate them, yet it in a remarkable manner hits upon the sense and upon the obscurity which hangs over it. "Do thou for me" —what shall he do? Why, do whatever he thinks fit. He leaves himself in the Lord's hands, dictating nothing, but quite content so long as his God will but undertake for him. His plea is not his own merit, but the name. The saints have always felt this to be their most mighty plea. God himself has performed his grandest deeds of grace for the honour of his name, and his people know that this is the most potent argument with him. What the Lord himself has guarded with sacred jealousy we should reverence with our whole hearts and rely upon without distrust. "Because thy mercy is good, deliver thou me." Not because I am good, but because thy mercy is good: see how the saints fetch their pleadings in prayer from the Lord himself. God's mercy is the star to which the Lord's people turn their eye when they are tossed with tempest and not comforted, for the peculiar bounty and goodness of that mercy have a charm for weary hearts. When man has no mercy we shall still find it in God. When man would devour we may look to God to deliver. His name and his mercy are two firm grounds for hope, and happy are those who know how to rest upon them.
