Questioning God's Faithfulness

Psalms 77:5-9

I think about the days of old, the years of long ago;

in the night I remember my song, I commune with myself, my spirit inquires:

"Will Adonai reject forever? will he never show his favor again?

Has his grace permanently disappeared? Is his word to all generations done away?

Has God forgotten to be compassionate? Has he in anger withheld his mercy?" (Selah)
