Psalm 13:1-6, ESV
To the choirmaster. A Psalm of David. How long, O LORD? Will you forget me forever? How long will you hide your face from me? How long must I take counsel in my soul and have sorrow in my heart all the day? How long shall my enemy be exalted over me?
Consider and answer me, O LORD my God; light up my eyes, lest I sleep the sleep of death, lest my enemy say, “I have prevailed over him,” lest my foes rejoice because I am shaken.

But I have trusted in your steadfast love; my heart shall rejoice in your salvation. I will sing to the LORD, because he has dealt bountifully with me.

Psalm 13:1-6, JN paraphrase
Haven’t we all be through this? When our self-pity exceeds our good sense; when Satan sticks a knife in our ego and twists?

But the lesson David shares with us is to steadfastly dwell on the power of His word and trust in the permanence of His word.

And He does enjoy the prayers and songs of His saints.
