John tells us that Jesus — called 'the Word' — was with God before anything was made and is God Himself. Jesus came into the world as a real person, but many did not recognize Him. John the Baptist pointed to Jesus as the Lamb of God. The first disciples heard about Jesus and began to follow Him.
Jesus, God's own Son, came to live with us as a person so we could know and love God.
John 1 opens with some of the most profound theology in the Bible. John uses 'the Word' (Greek: Logos) to describe Jesus — a title that would have meant 'divine reason and communication' to Greek-speaking readers, and 'God's spoken creative power' to Jewish readers. For children, the key idea is simple and breathtaking: Jesus always existed with God, was there when everything was made, and then became a real human being so we could know God personally. Emphasise that Jesus is not a created being — He is the Creator. The calling of the first disciples shows us that Jesus invites everyone personally: 'Come and see.'
Jesus was not just a good teacher who lived a long time ago — He is the eternal Son of God who became a person because He loves you. You can come to Him and He will welcome you.
