What does the Bible say about the security of the church?

According to Scripture, the security of the church is intimately tied to its foundation, which is Jesus Christ. As stated in Isaiah 28:16, God promised to lay a precious cornerstone in Zion, and those who believe in Him will never be put to shame. This underlines the church's foundation not being a mere human structure, but an eternal, divine establishment placed by God Himself. The church comprises true believers who have been redeemed and justified through Christ's sacrifice, emphasizing its spiritual nature over any physical building.
