Matthew 7:21-23
Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven. Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works? And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.
It is not enough to just say that you follow Christ and then half way do it. You must follow his commandments and follow his gospel. We have to follow Christ’s plan of salvation, not make up our own. There will be many people who do not make it into heaven that thought they were doing the right things. It is is important that we study and read Christ’s words to find the correct way.
