In this study, the Apostle Paul teaches that God has lavished His grace on believers by giving them wisdom and understanding through the revelation of the mystery. This mystery explains God’s purposes for heaven and earth and shows that the Body of Christ has a heavenly inheritance, predestined to share in Christ’s glory. Believers are eternally secure because, after hearing and believing the gospel, they are sealed with the Holy Spirit. Paul rejoices in these blessings and gives thanks for the Ephesians’ faith and love, urging believers to live daily in trust because of their secure position in Christ.
