The soul's appeal to God.
The groundwork of the psalm is that of great affliction. The psalmist is in very sore trouble; the strongest expressions are used to convey the idea of complete outward disaster and inward dejection (Psalms 143:3, Psalms 143:4). There is only one respect in which things could be worse than they are—death itself, and the going down into the dark land of forgetfulness (Psalms 143:7). But, as in the preceding psalm, his dire extremity is the very occasion for holy trust in the almighty power and unfailing righteousness of Jehovah. His refuge is in God. Here, indeed, is a strong Rock in which to hide in this dark night of trouble. We have—
I. HIS RELIANCE ON ALL THAT HE KNOWS OF God.
1. He remembers what God has been to him and has done/or him and for others in past days; what "doings," what "works," what deliverances he wrought in "the days of old" (Psalms 143:5). "Thou hast been my help," etc. (Psalms 27:9).
2. He relies on the known character of God; his loving-kindness (Psalms 143:8); his faithfulness, his perfect trueness to his word of promise; his righteousness, his constant readiness to reward those who seek him and serve him, and his determination to punish the wicked. These recognized and steadfast attributes of God are to him a strong security. God cannot be inconsistent with himself.
II. HIS CONSCIOUSNESS OF INTEGRITY. The writer would not dare to make his appeal to the Holy One if he himself were living in sin. He knows well that the man who purposes to continue in rebellion against God, or in rejection of his offered mercy, has no ground on which to stand (see Psalms 66:18; Psalms 1:1-6:16). Not, indeed, that he claims absolute inerrancy or perfection; he knows that such purity is beyond him (Psalms 143:2); but at the same time, he is conscious of moral and spiritual integrity; he is God's servant (Psalms 143:12). The purpose of his heart is toward God and the keeping of his commandments. He intends to walk uprightly and holily before God, to the full height of his strenuous endeavor. His God is the Lord, and no other lord shall have dominion over him.
III. THE FULNESS OF HIS APPEAL
1. He prays God to "quicken" him, to reanimate him, to fill his soul with courage and with hope, that he may play a brave and manly part.
2. He prays for deliverance from his evil estate; for the confusion of his enemies; for restoration to peace and joy (Psalms 143:9, Psalms 143:11, Psalms 143:12).
3. He prays to be led forward in his rectitude, that he may fulfill all God's holy will concerning him (Psalms 143:10). We cannot hope to rise higher than the spirit shown in this devout desire. It is right to wish and to ask, with all filial deference, for recovery from sickness, or for rescue from bondage, or for deliverance from anxiety or poverty; but it is a loftier and worthier aspiration to long to be led by the good Spirit of God into "the land of uprightness," into a state of lull acquiescence with the will of God, into a spiritual condition in which the doing or the bearing of the will of God is the supreme aim and endeavor of the soul.
IV. HIS EARNESTNESS. (Psalms 143:6-8.) There is every indication here of great earnestness of spirit. His soul thirsts for God's interposition as a parched land for water; he cries for a speedy response to his appeal; he yearns to hear God's loving-kindness "in the morning," and "lifts up his soul" unto God. Everything is to the earnest. Lukewarmness is offensive to God, as we learn from the risen Savior. A spasmodic piety, a fitful enthusiasm, will accomplish nothing for ourselves or for the world. It is steadfast purpose and sustained devotion that rises to the high tablelands of exalted worth and abounding fruitfulness.
