“The Trinity is not an abstraction but a living, working, Creator-Redeemer. God is who he is in his triune being for our salvation. We are chosen by God the Father, in Christ the Son, through God the Holy Spirit. Salvation is administered by the Father, accomplished by the Son, and applied by the Spirit. To express the same truths in yet another way, the salvation that was planned by the Father has been procured by the Son and is now presented and protected by the Spirit. Whatever words we use to describe it, the point is that our salvation from sin depends on a gracious cooperation within the Godhead.”

– Phil Ryken, Our Triune God, 21.
