In his biography of Jonathan Edwards, page 497, George Marsden writes, "In the Edwardses' world, the meaning of life was found in intense loves, including earthly loves." It was the tone of their life together. They understood that God is of such a nature, creation is for such a purpose, redemption is of such a power, that intensity of love is the meaning of it all. Intensity. Passion. Wholeheartedness.
Deuteronomy 6:5 makes intense love the greatest commandment: "You shall love the Lord your God with all your heart and with all your soul and with all your might." Moderate love is a sin. Maybe the worst sin.
As Augustine said, "Give me a man in love. He knows what I mean."
