This verse is key. Know and acknowledge Jesus is the Son of God. If you do that, God lives in you. Think about that. God, who created the universe and everything in it, will live in you. He will live in you through his Holy Spirit.
How awesome is that? Stop. Think about it. Let it sink in for a few minutes. God wil live in you. You will live in and through God.
Know that Jesus is the Son of God.
