3 Keypoints From: Content vs Container
It doesn't matter if everyone in the world thinks that a fellow is the closest person to Jesus Christ. If he or she is not truly born again, Jesus will deny the fellow on the last day.
Don't pretend to be a Christian, genuinely give your life to Christ if you haven't done so and live a holy life henceforth. You cannot call Jesus 'Lord' and keep on obeying the devil.
Make your inside clean first, and then the outside will be clean as well. It is not the other way round.
“Some people can deceive the whole world with their container, but that will only put them in more trouble because it will become more difficult for them to get on the right track with God.”
Memorise: Having a form of godliness, but denying the power thereof: from such turn away. (2 Timothy 3:5)
