How do we know God's truth is revealed in the Scriptures?

Believers uphold that the Scriptures are the ultimate source of God's revelation. According to the sermon, God's authority is reflected in His Word, which contains the teachings of Christ and the writings of the apostles. The preacher emphasizes that any teaching not aligned with Scripture lacks true light, affirming that the Bible should be the foundation upon which all understanding of God’s truth is built. This assurance is rooted in the belief that God is sovereign and has never erred in His communication.
