This was part of the first sermon (He Has Made Himself Known) that didn’t make it to the final cut that I thought was pretty interesting.
John’s gospel starts with “In the beginning” – does that sound familiar? That's how the Bible begins with Genesis 1:1. In the beginning, God created. The first thing He created was light. And the story begins with a man named Adam, the first human being.
John's Gospel starts in the beginning, also talks about creation, and talks about Jesus Christ, who the Bible calls the true light and the second Adam (Romans 5). The first Adam brought sin and death into the world, the second brought salvation and life.
So John, in telling us how Jesus revealed Himself, draws many parallel truths from Genesis. One more reason that I personally believe that Genesis is literal history!
