Human Depravity is a salutary doctrine

It is a salutary doctrine - one which God often uses to bring men to their senses. While we imagine that our wills have power to do what is pleasing to God, we never abandon dependence on self. Not that a mere intellectual knowledge of man’s fall and ruin is sufficient to deliver from pride. Only the Spirit’s powerful operations can effect that: yet He is pleased to use the faithful preaching of the Word unto that end. Nothing but a felt sense of our lost condition lays us in the dust before God.
