Because of the LORD’s great love we are not consumed,
for his compassions never fail.
They are new every morning;
great is your faithfulness.
-- Lamentations 3:22-23
God's mercies are new every morning because we get up rarin' to newly sin.
But if you are in Christ Jesus, you wake up each morning with nothing left to prove to God. Clothed in his righteousness, eye boogers and morning breath and coffeeless grouchiness and all, you wake up approved.
