Yes, it’s true that many times we bring on our own misery (5:7, etc), but many times our misery is brought about because we live in an imperfect world.
Whatever the cause, God can use our tragedy to bring us into a closer relationship with God. We learn that we are not in total control, and that God sometimes is ALL we can trust in, for our ETERNAL happiness.
We recognize that THIS world is not our ultimate home, but heaven is (as Job wished existed in 14:14), that THIS world is frequently “not fair”, (Chapter 21) but that God is always with us even when (especially when!) it seems God is not. (9:11,23:8)
We don’t need to know all God’s answers (42:1-6), we just need to trust God.
“Be still, and know that I am God.”
