How do we know Christ builds His church?

Christ's declaration in Matthew 16:18, "I will build my church; and the gates of hell shall not prevail against it," assures us that His church is divinely established and sustained. This promise reveals His sovereign authority over the church and guarantees its ultimate victory against all opposition. Furthermore, the metaphor of the church as a spiritual house being constructed of lively stones (1 Peter 2:5) underscores that the building process is overseen by Christ, who chooses those who will be part of His body. His unwavering commitment to the church highlights His role as both the architect and sustainer.
