3B Truth in 1 Timothy 3:15 refers to the real things revealed in God’s Word, which are mainly Christ as the embodiment of God and the church as the Body of Christ—2:4; Col. 2:9, 19.
4C The truth is the Triune God, having Christ as the embodiment, center, and expression to produce the church as the Body of Christ, the house of God, and the kingdom of God—v. 9; Eph. 1:22-23; 4:16; 1 Tim. 3:15; John 3:3, 5.
6E As the pillar that bears the truth and the base that upholds the pillar, the church testifies the reality, the truth, of Christ as the mystery of God and the church as the mystery of Christ—Col. 2:2; Eph. 3:4.
7F The kind of church that we build up depends on the kind of truth that we teach; thus, there is the desperate need of the living truth to produce the church, to help the church to exist, and to build up the church—1 Tim. 3:15.
