How do we know that the Church cannot be destroyed?

The assurance of the Church's indestructibility is rooted in Matthew 16:18, where Jesus declares that the gates of hell shall not prevail against it. Unlike the physical Temple, which was destroyed, the Church is built upon Christ, the Chief Cornerstone, and thus it possesses a divine safeguard. The Church may face challenges and persecutions, yet its foundation in Christ guarantees that it will ultimately prevail, as God continuously protects and preserves His people against all adversities.
