Psalms Chapter 61
Psalm 61. The main point of all these psalms is trust in God when all is against the godly One. The more all circumstances are adverse, the more God is trusted in; but Christ shines through all as taking the dependent godly one's place. Many of the psalms of this book were, it is very likely, composed when David was driven out through Absalom.
This confidence in God which calls Him to hear is expressed in Psalm 61. It is not an appeal of the godly man against enemies, but the sinking of his heart as cast out; but, when at the end of the earth and his spirit overwhelmed, he cries to God and looks for a rock higher than himself from this flood. Thus his confidence was restored. It was a known God whom he thus trusted, whatever his then sorrows. In Verse 5 (Psa 61:5) he applies it to present certainty of having been heard. The vows he had sent up Godward had reached His ear above; full blessings would rest upon him, and in those blessings he would perform them. Verse 6, (Psa 61:6), doubtless, as to the occasion of it, was David, but it looks, I apprehend, clearly to a greater than he, and the abiding life into which He entered as man; and though the godly remnant be thus driven out and their spirit overwhelmed within them, yet the fact that the King had been so would be a cheer and a security to their hearts: His song would become theirs, His having sung it a relief to them when they might have sunk in despondency. Though the being driven out is the occasion and is felt, the psalm does not refer to wickedness, but to nature, the human heart being overwhelmed.
