We say, then, that Scripture clearly proves this much, that God by his eternal and immutable counsel determined once for all those whom it was his pleasure one day to admit to salvation, and those whom, on the other hand, it was his pleasure to doom to destruction. We maintain that this counsel, as regards the elect, is founded on his free mercy, without any respect to human worth, while those whom he dooms to destruction are excluded from access to life by a just and blameless, but at the same time incomprehensible judgment
John CalvinFor until men recognize that they owe everything to God, that they are nourished by His fatherly care, that He is the Author of their every good, that they should seek nothing beyond Him - they will never yield Him willing service. Nay, unless they establish their complete happiness in Him, they will never give themselves truly and sincerely to Him.
John CalvinWhomever the Lord has adopted and deemed worthy of His fellowship ought to prepare themselves for a hard, toilsome, and unquiet life, crammed with very many and various kinds of evil.
John Calvin
