“The kingdom of God is central in Jesus’ teaching, where it refers not primarily to a geographical realm and its people but rather to the exercise of God’s sovereign power or rule.”

— Carl F.H. Henry, Has Democracy Had Its Day? (Nashville: ERLC, 1996), 4.

What reward shall I give unto the Lord for all the benefits that he had done unto me? In the first creation, He gave me myself; but in His new creation He gave me Himself, and by that gift restored to me the self that I had lost. Created first and then restored, I owe him myself twice over in return for myself. But what I have to offer Him for the gift of Himself? Could I multiply myself a thousand-fold, and then give him all, what would that be in comparison with God?
– Bernard of Clairvaux (1090-1153), On Loving God, 5
