If you do not believe the Bible, you are not a Christian. As Jesus says, “If you continue in My Word, then are you my disciples indeed. And you will know the truth and the truth will set you free.” (John 8:32)
“Not everyone who says to me, ‘Lord, Lord,’ will enter the kingdom of heaven, but only he who does the will of my Father who is in heaven. Many will say to Me on that day, ‘Lord, Lord, did we not prophesy in Your name, and in your name drive out demons and perform many miracles?’ Then I will tell them plainly, ‘I never knew you. Away from me, you evildoers!” (Matthew 7:21-23)
