God's ultimate purpose is to prepare a bride for his son. Believers are called to experience the same oneness as the Trinity - Father, Son and Holy Spirit. The key to unity and oneness is peace. When people receive salvation through Jesus Christ, God's wrath is turned away and they stand righteous before God. God desires for believers to know his oneness through walking in the peace of Christ. The witness of the church in the world depends on its effectiveness in being one with God.
