The church of God is built upon the foundation of apostles and prophets, with Jesus Christ as the Chief Cornerstone. As long as there is a church, there will be at least one living stone upon another, though the church will not always exist in the same form and may experience turmoil, division, and scattering due to carnality. Even in stable times, the church faces persecution from without, and the Good Shepherd moves His sheep in ways that are not always immediately understood. Jesus Christ gives gifts to men, such as apostles, prophets, evangelists, pastors, and teachers, for the edification and building up of the Body of Christ. As long as the Body needs edification and has not achieved the unity of the faith or the fullness of Christ, God will continue to work through such men to bring about that growth. The structure and cohesiveness of the church may vary across history, but where Christ's Body is found, there will be structure, as isolation leads to spiritual death. Prophetic visions in Zechariah and Revelation indicate that before Christ's return, a definite structure will be in place, with distinct groupings of churches or congregations existing during the Day of the Lord. These groupings are not in complete dissolution but show order and providential care by the Head, with the stones fitted together rather than isolated. Though physical organizations may rise and fall, the church of God, as a spiritual organism, will always maintain a unity of the Spirit and prevail against the gates of Hades.
