Psalm 30:5: Joy Comes in the Morning
Psalm 30:5 sets the night of weeping against the lifetime of God's favor, so the sorrow of the present is real but not final. The verse grounds morning joy in who God is, not in how long our night lasts.
From silent struggles to songs of praise
Psalm 40:1–3 does not end with a silent struggle. It shows a person waiting on Yahweh, being heard, lifted from the mud, set on rock, and given a song whose reach extends to everyone watching.
