Charles H. Spurgeon on Psalms 42:11

Why art thou cast down, O my soul? and why art thou disquieted within me? In the rehearsal of his sorrow, he finds after all no sufficient ground for being disquieted. Looked in the face, his fears were not so overwhelming as they seemed when shrouded in obscurity. Hope thou in God. Let the anchor still keep its hold. God is faithful, God is love, therefore there is room and reason for hope. Who is the health of my countenance, and my God. This is the same hopeful expression as that contained in verse five, but the addition of and my God shows that the writer was growing in confidence, and was able defiantly to reply to the question, "Where is thy God?" Here, even here, he is, ready to deliver me. I am not ashamed to own him amid your sneers and taunts, for he will rescue me out of your hands. Thus faith closes the struggle, a victor in fact by anticipation, and in heart by firm reliance. The saddest countenance shall yet be made to shine, if there be a taking of God at his word and an expectation of his salvation.

"For yet I know I shall him praise

Who graciously to me,

The health is of my countenance,

Yea, mine own God is he."
