We’re not fighting against human beings, but against the rulers, authorities, and powers of this dark world and against the spiritual forces of evil in the heavenly world.
Anyone who speaks a word against the Son of Man will be forgiven, but anyone who speaks against the Holy Spirit will not be forgiven, either in this age or in the one to come.
You were following the ways of this world and serving the one who rules over the spiritual forces of evil. That’s the spirit who’s still at work in those who aren’t obeying God.
