§ 02 · King James Bible
Romans 8:9
But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his.
Simple English
But you're not just physical beings; you're guided by the Spirit. If God's Spirit lives within you, then you belong to Christ. But if someone doesn't have Christ's Spirit, they don't belong to him.
