1 Therefore, having been justified by faith, we have peace with God through our Lord Jesus Christ, 2 through whom also we have access by faith into this grace in which we stand, and rejoice in hope of the glory of God. 3 And not only that, but we also glory in tribulations, knowing that tribulation produces perseverance; 4 and perseverance, character; and character, hope. 5 Now hope does not disappoint, because the love of God has been poured out in our hearts by the Holy Spirit who was given to us.
A well-grounded assurance of faith is a heaven of delight in the heart of believers this side of eternity. The Apostle Paul teaches that believers rejoice in tribulation because of the joy of a well-grounded assurance, an assurance enjoyed subjectively and grounded objectively on the Word and promises of God. The doctrine of justification should be embraced and relished such that it yields sweet comfort and consolation in our hearts by the power of the Holy Spirit, for we know that Christ’s perfect righteousness is imputed to believers and they will never perish. We can be free from the haunting guilt of past shame and the fear of death because our salvation is perfect, perpetual, and permanent, based on the righteousness of Jesus Christ alone.
