Why is it important for Christians to understand the mystery of Christ?

The mystery of Christ, as revealed in the New Testament, is significant because it unveils God's redemptive plan, which was once hidden but is now made known through the Gospel. Paul emphasized that this mystery includes the inclusion of Gentiles as fellow heirs in God's promise (Ephesians 3:6). By comprehending this mystery, Christians recognize their identity and standing before God, fostering a deeper appreciation for divine grace. This understanding also unifies believers, as they share in the hope and blessings confirmed in Christ, collectively reflecting God's glory.
