"Get behind me, Satan! For you are not setting your mind on the things of God, but on the things of man.”

Just remember that Jesus rebuked that at his disciple. Not even at the Pharisees. HIS DISCIPLE.

It's just as easy for us to think we're okay. Be warned.
When you're not setting your mind on how to live how God wants you to, when your minds are so busy pleasing yourself and everyone else on earth, you're doing Satan's work. If you care more about what people think than what God thinks, you're helping Satan. If you are living life more committed to your studies, your family, yourself... you might as well be the same as Satan himself. Be ashamed to call yourself a disciple of Jesus. Be completely remorseful at calling yourself a Christian.
