Predestination we call the eternal decree of God, by which He has determined in Himself, what He would have to become of every individual of mankind. For they are not all created with a similar destiny; but eternal life is foreordained for some and eternal death for others. Every man, therefore, being created for one or the other of these ends, we say he is predestinated either to life or to death.Institutes, Book III, Ch. XXI, Sec. 5.
Here is stated what the effect of predestination is. For the effect of predestination is that grace by which we are justified in the present and are assisted to live rightly and to persevere in the good, and also the grace by which we are blessed in the future.The Sentences, Book 1, Dist 40
