“My soul thirsteth for God, for the living God: when shall I come and appear before God?” (Psalm 42:2).

When? Well, I can go to God any time! (But I don’t, so no wonder my thirst isn’t quenched.)

“Why art thou cast down, O my soul? and why art thou disquieted within me? hope thou in God: for I shall yet praise him, who is the health of my countenance, and my God” (Psalm 42:11).

Why? Because my focus is on me, my problems and fears and worries, or on other people. (Trusting in God changes my perspective as well as my outlook.)

“O my God, my soul is cast down within me: therefore will I remember thee” (Psalm 42:6).

That’s what I need to do when I am cast down!

Surely you could add something...
