But mark, wherever the Spirit of God comes, He destroys the goodliness and flower of the flesh. That is to say, our righteousness withers as our sinfulness. Before the Spirit comes we think ourselves as good as the best. We say, “All these commandments have I kept from my youth up,” and we superciliously ask, “What do I lack?” Have we not been moral? No, have we not even been religious? We confess that we may have committed faults, but we think them very venial, and we venture, in our wicked pride, to imagine that, after all, we are not so vile as the Word of God would lead us to think.
Ah, my dear Hearer, when the Spirit of God blows on the comeliness of your flesh, its beauty will fade as a leaf, and you will have quite another idea of yourself. You will then find no language too severe in which to describe your past character. Searching deep into your motives, and investigating that which moved you to your actions, you will see so much of evil that you will cry with the publican, “God be merciful to me, a sinner!”
