Psalms 42:11

Why art thou cast down, O my soul, and why art thou disquieted, tossed and agitated like an angry sea, within me? Hope thou in God; for I shall yet praise Him, who is the Health of my countenance, his Help and Deliverance, who cheers him and drives away the clouds of sorrow from his face, and my God, to whom he clings despite the enemies' mockery, refusing to have doubt take the place of faith. Temptations caused by times of trouble can be overcome only by the believer's laying hold of God's grace as his one hope of salvation.
