I love how John right away places Jesus as in the beginning of creation, that makes Jesus eternal just as the Father is eternal. Also everything in life is created by Him and we would not be here if we had not been created of God. God is the God of yesterday, today, and all of our tomorrows. The plan in the beginning after the fall was to send Jesus so that we could have eternal life. Jesus is fully God. The Father, Son, and Holy Spirit are right there is verse 1. I am thankful in verse 2 that our God and Lord never changes, He is the same today as He was at the time of creation. Always loving us and drawing us toward Him. I love to say the great " I AM ", these two words say it all.
