Jesus uses this same model by calling-out members of this world into an ecclesia of His own. They are called-out and trained in his ways and then sent back to offer the governance of the Lord to the people of this world. The governance of the Lord is able to affect not only individuals, but also all spheres of society.
Jesus said that He would build His Ecclesia upon Himself, “the Christ, the Son of the living God” and that the gates of hell would not prevail against it. The purpose of Jesus’ Ecclesia is in the proclamation of this truth. We are to go into the world and proclaim that God’s promised Messiah has come, bringing people into relationship with the living God and under His loving rule.
The kingdom of God is offered and not forced onto people. Where it is accepted, the life of the Kingdom begins to take hold and transform lives and communities.
