How do we know Christ's teachings are true?

The teachings of Jesus are firmly rooted in the Old Testament Scriptures, which point to Him as the fulfillment of God's redemptive plan. Jesus Himself redressed the concerns of His disciples in Mark 13 by redirecting their focus from outward symbols of religion, like the temple, to Himself as the cornerstone of faith. The certainty of Christ's teachings can be observed through the accuracy of the prophecies He fulfilled and the spiritual truths He expounded. Ultimately, true faith rests on the belief in Christ as revealed in Scripture, making it necessary to understand and embrace His Word as the ultimate authority.
