The gospel of John begins the same way as the book of Genesis at the start of the Old Testament: in the beginning. John wants us to know that this is a testimony of the work of God that is just as important as that creation account written by Moses at the very beginning. The Word who was there in the beginning with God creating the world is the same Word who John writes about in His gospel. When we hear that God created everything by His Word, it means the Word, the Son of God.
