Paul reveals the mystery of the Church: through Christ, Jews and Gentiles unite as one body, sharing the promise of grace. Empowered by God’s grace, Paul proclaims the riches of Christ and emphasizes that through Jesus, we have confident access to the Father. He prays for believers to be strengthened by the Holy Spirit, rooted in love, and to understand the vastness of Christ’s love, being filled with God’s fullness. This mystery showcases God’s great power within us.
