In John 1:12-13, we come face to face with three radical truths regarding the centrality of God in salvation that are revealed through the person and work of Jesus.
In John 1:11, we see the Old Testament covenant pattern between God and Israel fulfilled.
The world of fallen humanity is not friends with God. This is what we see in John 1:10 where we are told that when God Himself came to the very world He had made, instead of welcoming Him and worshiping Him, it shunned Him.
John reiterates his identification of the Word as the true Light which enlightens every person.
