But God used a wicked king for His purpose, even set him up as a hero, a deliverer for His people. Your successes don’t necessarily define your character or your relationship with God.
We can’t say I’m good with God simply because we are used by God or God works through us. Neither does lack of apparent success always result from character flaws or indicate Kingdom failures.
God’s character forming in us and His Kingdom advancing through us come through both “success” and “failure.”
