Justification assures glorification
The gospel of grace and its resulting salvation is a gift that God freely provides to the one who believes in the cross work of Jesus Christ; that by His death we are forgiven and by His resurrection we are justified.
Paul provides us assurance of this perfect work to save us and bring us to peace and atonement with God. However, Paul continues to provide more details of this incredible gift of salvation. Read the two verses and let me elaborate on them,
Rom 5:1 Therefore being justified by faith, we have peace with God through our Lord Jesus Christ:
Rom 8:30 Moreover whom he did predestinate, them he also called: and whom he called, them he also justified: and whom he justified, them he also glorified.
God’s salvific work does not stop at our justification. The cross work of Jesus Christ was so complete and effectual that if utterly guarantees glorification to the one who believes in Christ. Did you get that? I’m going to say it again as it is worth reading again and its worth remembering that these are the inspired and assured words of God! “The cross work of Jesus Christ was so complete and effectual that to the one who believes in Christ it utterly guarantees their glorification.”
