Thus ends the Gospel of John.
Jesus of Nazareth is affirmed by John as the Christ. He is like none other. He is the Father personified as the Word, the Second Person of the Trinity. Because He is God His work, and His words are true. Because He is God His salvation is certain. The verdict that John’s evidence demands is, “Do you believe that Jesus is Lord?”
If you believe that faith will change your life and secure your destiny.
If you choose not to believe you will “perish”.
