The Father sends the Son and the Holy Spirit. The Son enters the arena of this world by incarnation voluntarily. He is no reluctant Redeemer. The Holy Spirit applies the work to us for our salvation. The Spirit does not chafe at doing the Father’s bidding. The Father is pleased to send the Son and the Spirit into the world, and they are please to carry out their respective missions.
