Everyone experiences disappointment or sadness to some degree. In Psalm 13, David demonstrated what it means to trust God in tough times. Feeling forgotten, forsaken, sorrowful, and subdued, David cried out for God’s consideration and illumination. As he prayed, his perspective changed, and he was able to rejoice—even though his circumstances remained the same. Alistair Begg teaches that when we face difficult times, we must resist self-pity, trusting that God knows what’s best for us and can use even our hard experiences for good.
