“Each of the three persons in the blessed Trinity is concerned with our salvation: with the Father it is predestination; with the Son, propitiation; with the Spirit regeneration. The Father chose us; the Son died for us; the Spirit quickens us.The Father was concerned about us; the Son shed His blood for us; the Spirit performs His work within us. What the one did was eternal, what the other did was external, what the Spirit does is internal.”
(From The Sovereignty of God, by A.W. Pink).
