Eternal life IS Jesus Christ, the only true and living God, KNOWING HIM and living in constant communion with Him. Those who KNOW Him and FOLLOW Him talk about Him. They tell the world about Him because they KNOW Him.
Many only know the Bible, many are only religious, that is all that they can talk about because they DO NOT KNOW JESUS CHRIST. They do not live in communion with Him.
Do you KNOW Jesus Christ? His sheep LISTEN to His voice and they FOLLOW Him every day. He IS their LIFE. Do you KNOW Jesus? Have you found the only true living God, Jesus Christ and are you living in CONSTANT COMMUNION with Him?
May Jesus bless you.
