How do we know that Christ preserves His church?

The preservation of the church is rooted in the promise of Christ to keep His people safe until the end. As emphasized in Revelation 3:10, Christ assures the faithful church at Philadelphia that He will keep them from the hour of trial, illustrating His authority over trials and tribulations. He promises to empower and preserve them, ensuring that they remain true to His Word and do not deny His name. This preservation is a testimony to God's grace, where He not only initiates the salvation of His people but also sustains them throughout their lives in faith. The doctrine of perseverance, especially in the Reformed tradition, reinforces that genuine believers will be kept in faith by the Holy Spirit, as noted in Philippians 1:6, which states that God will complete the work He began in them.
