Why is oneness with Christ important for Christians?

Oneness with Christ is foundational for Christian identity and security. In John 17:21, Jesus prays for His followers to be one, just as He and the Father are one. This relationship secures our position before God, as we are united in Christ’s righteousness and glory. It also reflects the nature of our salvation; through His grace, we are called to share in the divine life and fellowship of the Trinity. Furthermore, our oneness with Christ compels us to live in harmony with fellow believers and engage in the mission of the church, as we reflect the unity of the Godhead in a divided world.
