Why is the concept of one fold important for Christians?

The idea of one fold and one shepherd as stated in John 10:16 is vital for Christians as it signifies the unity that exists among all believers, irrespective of ethnic or cultural backgrounds. This unity is rooted in the reconciliation brought about by Christ’s death and resurrection, which dismantles barriers and allows all of God's people to gather together under the headship of Jesus. The Apostle Paul elaborates on this in Ephesians, where he discusses how Christ has brought peace, creating one new humanity out of the two (Jew and Gentile). This emphasizes the inclusive nature of the Christian faith, as all who trust in Christ belong to His one Church, having been chosen and redeemed by Him.
