Why is the mystery of the Gospel important for Christians?

The mystery of the Gospel refers to God's hidden purpose and plan of salvation that was revealed in Christ. As stated in Colossians 1:26-27, 'the mystery which hath been hid from ages and from generations, but now is made manifest to his saints.' This mystery is vital for Christians because it encapsulates the essence of their faith: redemption through Jesus Christ. Understanding this mystery assures believers of their position before God as chosen and redeemed. Additionally, it encourages them to share this truth with others, as Paul requested prayer for opportunities to declare the mystery of Christ (Colossians 4:3). The revelation of the Gospel informs the believer's identity, purpose, and hope, ultimately leading to a life of worship and service to God.
