â€œIf God contains the fullness of all good things in himself like an inexhaustible fountain, nothing beyond him is to be sought by those who strive after the highest good and all the elements of happiness â€¦ If the Lord will share his glory, power, and righteousness with the elect â€“ nay, will give himself to be enjoyed by them and, what is more excellent, will somehow make them to become one with himself, let us remember that every sort of happiness is included under this benefit.”
– John Calvin, Institutes of the Christian Religious, 3.XXV.10 (v2, p. 1005)
This is a staggering reality. Chew on it. Dwell in it.
