True disciples obey the teachings of Jesus
Matthew 7:21–23 (ASV)
21Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father who is in heaven. 22Many will say to me in that day, Lord, Lord, did we not prophesy by thy name, and by thy name cast out demons, and by thy name do many mighty works? 23And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.
