How do we know Christ is the way, the truth, and the life?

In John's Gospel, Jesus explicitly declares Himself as 'the way, the truth, and the life' (John 14:6). This proclamation affirms that He is not merely a guide but the definitive path to the Father. Throughout the sermon, it is reiterated that Christ's teachings are rooted in the righteousness and wisdom of God, making Him the ultimate authority on truth. Additionally, the consistency of His life and message, culminating in His sacrificial offering, underlines His truthfulness and authority. The discernment of His followers is enhanced through the revelatory work of the Holy Spirit, who brings an understanding of who Christ is and what He has accomplished for us.
