Many people profess to be Christians but we will know them by their fruits. Only those that acknowledge Christ as their personal Savior and follow His teachings and His Word daily are Christians - the others are CINO. That is where the word Christian comes from - Christ. Remember the passage..."I never knew you".
That said, there are those that are blinded with scales on their eyes. No words can penetrate their blindness. And we have seen that here first hand! As you know, God's Word is true - all the time, every time!
