" The spirit we long to see in our people must be in ourselves first. But that will never happen until, as Edwards says, we know our own emptiness and helplessness and terrible sinfulness. Edwards lived in a kind of spiraling oscillation between humiliation for his sin and exultation in his Savior. He describes his experience like this: Often since I lived in this town, I have had very affecting views of my own sinfulness and vileness; very frequently to such a degree as to hold me in a kind of loud weeping, sometimes for a considerable time together; so that I have often been forced to shut myself up.43 It is not hard to imagine the depth of earnestness that this kind of experience brought to the preaching of God’s Word. But of course one is on the precipice of despair when one focuses only on sin. This was not Edwards’s aim nor his experience. For him there was a response to guilt that made it an intensely evangelical and liberating experience: I love to think of coming to Christ, to receive salvation of him, poor in spirit, and quite empty of self, humbly exalting him alone; cut off entirely from my own root, in order to grow into, and out of Christ; to have God in Christ be my all in all.44 "
