A little book of just five chapters in the Old Testament is Lamentations. It’s the lamentations (meaning sorrow, or mourning) of Jeremiah the prophet as he mourning over the destruction that is coming to his people. He mourns because they brought the destruction upon themselves because of their sins and refusal to follow God.
In Chapter 3, Jeremiah describes the most devastating circumstances. He says that God has brought wrath upon him, brought him into darkness and not light, broken his bones, put a hedge around him so he can’t get out, made his chain heavy, left him desolate, made him a laughing stock to everyone, filled him with bitterness. He says he forgot prosperity. In verse 18, he says “My strength and my hope is perished from the Lord”.
But then he had a realization in 3:21-25:
21 This I recall to my mind, therefore have I hope.
22 It is of the Lord’s mercies that we are not consumed, because his compassions fail not.
23 They are new every morning: great is thy faithfulness.
24 The Lord is my portion, saith my soul; therefore will I hope in him.
25 The Lord is good unto them that wait for him, to the soul that seeketh him.
It reminds us that no matter how bad the circumstances (even if we caused the circumstances), God still shows his mercies.
God is good to them that wait for him, to them that seek him.
