How do we know that Christ's teachings are true?

The validity of Christ's teachings is supported by His miraculous works and the confirmation from God. In John 3:2, Nicodemus acknowledges that no one can perform the signs that Jesus does unless God is with him. Furthermore, Jesus consistently pointed to Old Testament scriptures that foretold of His coming and mission, thereby establishing His identity as the promised Messiah and Savior. The consistency in Scripture, alongside the miraculous validation during His ministry, assures believers of the truth of His teachings and their foundational role in the Christ-centered faith.
