How do we know the faith is being preserved?

The preservation of the faith is rooted in the belief that Scripture alone is authoritative and sufficient for all matters of faith and practice. This is encapsulated in the phrase 'Sola Scriptura,' which emphasizes that God's Word does not change and provides the foundation for sound doctrine. As mentioned in the sermon, the Apostle Paul instructs Timothy in 2 Timothy 4:2 to 'preach the word,' indicating that true teaching must align with and be derived from Scripture, ensuring that the faith is guarded against falsehoods and remains intact throughout the ages.
