Charles H. Spurgeon on Psalms 38:9

Lord, all my desire is before thee. If unuttered, yet perceived. Blessed be God, he reads the longings of our hearts; nothing can be hidden from him; what we cannot tell to him he perfectly understands. The psalmist is conscious that he has not exaggerated, and therefore appeals to heaven for a confirmation of his words. The good Physician understands the symptoms of our disease and sees the hidden evil which they reveal, hence our case is safe in his hands. And my groaning is not hid from thee.

"He takes the meaning of our tears,

The language of our groans."

Sorrow and anguish hide themselves from the observation of man, but God spies them out. None more lonely than the broken hearted sinner, yet hath he the Lord for his companion.
