We are the city of the living God. You are a new creation. You have the Spirit. You live in the Spirit. You walk in the Spirit. You are empowered by the Spirit. You have a new life in Jesus. Flesh produces flesh, but the Spirit produces LIFE. There is a world of difference between the two. When Jesus spoke to Nicodemus, He was showing him that man-made religion can only produce flesh, but the Spirit is something completely different. He was inviting Nicodemus to taste something much different than he was aware of. First Corinthians 2:12-3:3 talks about how we have received not the spirit of the world, but the Spirit who is from God, that we might know the things that have been freely given us by God.
