John 17:21
That they all may be one; as thou, Father, art in me, and I in thee, that they also may be one in us: that the world may believe that thou hast sent me.
John 17:21
This verse shifts from individual unity to corporate, divine-human unity: that all may be one, just as Father and Son are one. The oneness Jesus prays for has ecclesiological and missional dimensions: unity among believers is a powerful apologetic and a sign to the watching world of God’s sending of Christ. This oneness is grounded in a shared source—the Father, Christ in the Son—producing visible harmony, mutual love, and cooperative mission. Unity here is not uniformity but a deep, transformative communion that reflects Trinitarian life in the church.
Unity is both a gift and a calling. It testifies to the truth of the gospel, demonstrates the power of the Spirit, and enables effective witness to the world. The unity enabled by the Spirit serves as a sign pointing to Jesus’ mission and love.
- Pursue reconciliation and humility in relationships within churches and denominations.
