Charles H. Spurgeon on Psalms 52:9

I will praise thee for ever. Like thy mercy shall my thankfulness be. While others boast in their riches I will boast in my God; and when their glorying is silenced for ever in the tomb, my song shall continue to proclaim the lovingkindness of Jehovah. Because thou hast done it. Thou hast vindicated the righteous, and punished the wicked. God's memorable acts of providence, both to saints and sinners, deserve, and must have our gratitude. David views his prayer as already answered, the promise of God as already fulfilled, and therefore at once lifts up the sacred Psalm. And I will wait on thy name. God shall still be the psalmist's hope; he will not in future look elsewhere. He whose name has been so gloriously made known in truth and righteousness, is justly chosen as our expectation for years to come. For it is good before thy saints. Before or among the saints David intended to wait, feeling it to be good both for him and them to look to the Lord alone, and wait for the manifestation of his character in due season. Men must not too much fluster us; our strength is to sit still. Let the mighty ones boast, we will wait on the Lord; and if their haste brings them present honour, our patience will have its turn by and by, and bring us the honour which excelleth.
