And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent.
Here is a simple explanation of how eternal life is obtained. It is by knowing God and Jesus Christ. The fact that the name of Jesus Christ is mentioned together with God the Father, as being the joint source of eternal life, means that they are equal. Here the Lord called Himself, Jesus Christ. The name Christ is the same as Messiah. This verse disproves the charge that Jesus never claimed to be the Messiah.
