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.

The concept of church structure emerges through the extended metaphor of a building possessing integrity, connecting personal character to the collective nature of the body of Christ. This theme is introduced by contrasting the honesty of Ted Williams, who voluntarily cut his own contract by nearly 30 percent because he felt he had not earned his previous salary, with the general scarcity of integrity found both in society and within various walks of life. Integrity is defined through Roget's Thesaurus as honesty, uprightness, moral soundness, principle, character, decency, and righteousness, and also as a refusal to lie, blame, or evade accountability. This personal definition of integrity is linked to Ephesians 6:10-14, where Paul instructs believers to stand firm against the schemes of the devil by putting on the whole armor of God, particularly the breastplate of righteousness, which the Phillips translation renders as the breastplate of integrity. This breastplate protects the heart, the seat of emotions, and without it, believers become vulnerable to being swayed away from truth. The discussion then expands integrity beyond individual character to a second meaning: the structural soundness of a building, which implies reliability, completeness, wholeness, strength, and unity. Ephesians 2:19-22 is used to illustrate this, describing believers as fellow citizens with the saints, part of a household of God built upon the foundation of the apostles and prophets, with Christ Jesus as the cornerstone. Each separate piece of this building fits properly into its neighbor, growing together into a temple where God dwells by His Spirit. This building metaphor is applied to believers who come from diverse backgrounds, education, and life experiences, yet must unite as fitted pieces of the Temple, each contributing personal integrity to form a sound and unified whole. Peter's parallel use of the building metaphor in 1 Peter 2:1-5 reinforces this point, describing believers as living stones being built into a spiritual house and holy priesthood, requiring the laying aside of malice, deceit, hypocrisy, envy, and evil speaking. Ephesians 3:17-19 continues this imagery, connecting the protected heart with being rooted and grounded in love, comprehending the dimensions of Christ's love, and being filled with the fullness of God, again invoking the language of building something solid and stable. The danger of structural failure is illustrated through the account of the Ted Williams Tunnel collapse in Boston, where fraud, deceit, and inferior materials led to a fatal accident when a steel tie-back failed under a concrete ceiling panel. This tragedy demonstrates that a lack of integrity in even one component—whether a support beam or a single contractor's shoddy workmanship—can compromise the entire structure, endangering lives. This is applied directly to the church: each member is responsible for building personal integrity using the abilities God has given, because if all operate with honesty, moral soundness, and righteousness, they fit together as a temple with true integrity, a fit habitation for God. The Moffatt translation of Ephesians 2:19-22 reiterates this closing image, describing believers as strangers no longer, welded together into a sacred temple in the Lord, and built together as a habitation for God in the Spirit.
