Faith without works is dead. It is very good to believe in God and to know about God, but God says that you must believe on Him and know Him personally. There must be an action that goes with that faith. The action is the doing what God says to do.
Devils worshippers go to a church.
You have to ask Jesus into your heart and make Him Lord and Savior of your life. The only way that someone can go to heaven is to be saved through faith, this verse clearly says that it is not how good of a person you are, how many good things you have done, or how many church services you have attended in your lifetime, but rather it clearly says that it is only by asking Jesus into your heart. Let me ask you this. If all it took to get to heaven was going to church, then why would God have had to send His one and only Son to die for you and me. If all we had to do was go to church,then Him dying on the cross was pointless.
