How do we know that Jesus' teachings on faith are true?

Jesus' teachings are confirmed through numerous scriptural accounts, where miracles and fulfillments of prophecies authenticate His divine authority. The assurance of the truth of His teachings also comes from the work of the Holy Spirit, who reveals the truth of God's Word to believers. Moreover, through historical accounts and personal experiences of faith, believers can testify to the power and reliability of Christ's promises. This interplay of Scripture, experience, and the Spirit provides a firm foundation for trust in Jesus' teachings.
