How do we know the doctrine of the church as the temple of God is true?

The doctrine that believers collectively form the temple of God is substantiated by various biblical passages. For example, 1 Peter 2:5 describes believers as 'lively stones' being built up a spiritual house, while Ephesians 2:22 reveals that the church is 'a habitation of God through the Spirit.' Furthermore, in Hebrews 9, the physical temple is presented as a foreshadowing of Christ and His church. The transformation from a physical temple to a spiritual one was clarified by Jesus Himself when He stated, 'Destroy this temple, and in three days I will raise it up' (John 2:19), referring to His body. This teaching is foundational in understanding the church's role in God’s redemptive plan.
