Christian living must be founded upon self-abhorrence and self-distrust because of indwelling sin's presence and power. Self-confidence and self-satisfaction argue self-ignorance. The only healthy Christian is the humble, broken-hearted Christian.--J. I. Packer, A Quest for Godliness: The Puritan Vision of the Christian Life (Crossway, 2010; repr.), 196
It is after he sees God, is made whole again, regains his sanity, and has his complaining heart drained of its incessant bickerings, that Job says: 'I despise myself, and repent in dust and ashes' (Job 42:6). That is the healthiness where Job ends; it is not an un-healthiness that Job needs to be cured of.
