The work of the Father in predestining, the work of the Son in redeeming, and the work of the Spirit in assuring believers are gloriously weaved together! None of Christ’s work can be severed from the Father’s sovereign choice in salvation or the Spirit’s guarantee of our inheritance.
Redeem means "to buy back". 1 Cor. 6:19-20, “You are not your own, for you were bought with a price.” Every created thing belongs to God, because God is the Creator of it all, but that doesn’t mean that all people are His children. If all were His children, then all would be saved, but all are not saved.
Christ’s sacrifice is sufficient to save all who believe.
- John 3:16, “whosoever believes in Him…will have eternal life”.
- John 6:47, “Truly, truly, I say to you, whoever believes has eternal life.”
- Acts 16:31, “Believe in the Lord Jesus, and you will be saved”.
So does the death of Jesus Christ make us save-able, or does it make us saved? Let's be clear, Jesus went to the cross assured of what He would do and how His sheep will respond (Jn. 10:15). If you believe, your sin has been forgiven – nailed to the cross – by the redeeming blood of Jesus. God has revealed His eternal & unchanging plan and it revolves around His Son, the Redeemer.
The Holy Spirit is the “guarantee of our inheritance", to the praise of His glory. Believer – your standing before God is sure because of the indwelling guarantee of the Spirit and the work of Christ as our constant Advocate.
