Those who live following their sinful selves think only about things that their sinful selves want. But those who live following the Spirit are thinking about the things the Spirit wants them to do.
But Jesus turned and looked at his followers. Then he told Peter not to talk that way. He said, “Go away from me, Satan! You don’t care about the things of God, but only about things people think are important.”
But you are not ruled by your sinful selves. You are ruled by the Spirit, if that Spirit of God really lives in you. But the person who does not have the Spirit of Christ does not belong to Christ.
A person who does not have the Spirit does not accept the truths that come from the Spirit of God. That person thinks they are foolish and cannot understand them, because they can only be judged to be true by the Spirit.
Our sinful selves want what is against the Spirit, and the Spirit wants what is against our sinful selves. The two are against each other, so you cannot do just what you please.
That punishment is especially for those who live by doing the evil things their sinful selves want and who hate authority. These false teachers are bold and do anything they want. They are not afraid to speak against the angels.
