Charles H. Spurgeon on Psalms 143:7

The prayer of David becomes, as he proceeds, both more spiritual and more fervent. In the sixth verse we find him thirsting after God; and now that thirst is become so intense that it admits of no delay. In the beginning of the psalm he was content to say, "Hear my prayer"; but now he cries, "Hear me speedily." This is not the language of sinful impatience: it is, indeed, good that a man should both hope and quietly wait for the salvation of God; yet a man may desire, not only an answer, but also a speedy answer, without incurring the charge of impatience. Whatever a man desires to have he desires to have soon; nor can he be otherwise than grieved at anything which delays the accomplishment of his wishes. In such desire or grief there is nothing sinful, provided it do not lead to murmuring or distrust of God. Hence this petition for speedy relief, and manifestation of God's presence and favour is very frequent with the Psalmist. He often prays, "Make haste, O Lord, to deliver; make haste to help me, O Lord." Nay, if a man does not desire the light of God's countenance soon, it is a certain proof that he does not desire it at all. If the natural language of his heart be not, "hear me speedily", delay is to him no exercise of patience. The very idea of patience implies that something is contrary to our wish; and the stronger the desire is, the more difficult will that exercise of patience become. "Hope deferred maketh the heart sick"; and therefore David adds, "my spirit faileth." He believed verily to see the goodness of the Lord in the land of the living; yet so intense was his desire, that faith could hardly keep his spirit from fainting, while the blessing, which he so eagerly pursued, seemed still distant, and fled before him. He is afraid lest if God should long delay, and withdraw himself, faith and hope could hold out no longer. He therefore pleads, "hide not thy face from me, lest I become like them that go down into the pit"; and urges the failing of his spirit before him who" will not contend for ever, lest the spirit should fait before him." —John Fawcett.

Verses 7-8, 10-11. Observe how David mixes together prayers for joy, for guidance, and for sanctification —"Hide not thy face from me." "Cause me to know the way wherein I should walk." "Teach me to do thy will." "Cause me to hear thy loving kindness in the morning." "Quicken me, O Lord, for thy name's sake." Now this is exactly right: our prayers, as well as our other obedience, must be without partiality; nay, we should desire comfort for the sake of holiness, rather than holiness for the sake of comfort. —John Fawcett.
