“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 13:5-6).
Once again, these verses come as something of a reversal at the end of the psalm. But this time it is a very short psalm, and so the passage from desperation (vv.1-2) to supplication (vv.3-4) to hope and praise (vv.5-6) is rather tight. David endures grief and scorn, and God seems distant; but, rather than despair, he calls out to God for deliverance. His confidence enables him to glorify the God of his salvation, whose mercies do not fail.
What is the believer’s confidence, when God seems distant and trouble seems triumphant? God’s love persists. We stumble and fail, but God always accomplishes His purpose, God is always true to His word, God guards and redeems His people. If we know this, can we find the depth of hope these verses describe, to cry out to God not only with requests and longings, but with joyful praise in His gift of salvation? God is faithful.
