How do we know Christ's words are true?

We know Christ's words are true because they are rooted in His divine nature and the authority of God's Word. In John 6:63, Jesus states, 'The words that I speak unto you, they are spirit, and they are life.' This means that His teachings are not mere human opinions; they are infused with divine truth and purpose. Furthermore, God's faithful fulfillment of His promises throughout Scripture serves as an assurance that what Christ says is trustworthy. Those who come to Him understand the necessity of His words as they lead to eternal life.
