Matthew 7:21-23 is one of the most alarming passages in the Bible. It warns that not everyone who claims Jesus as their Lord is sincerely saved. This means that many think they know Christ, but will come to find out that they never truly knew Him in a saving way.  Jesus then goes on to say that only those who do God's will is truly saved. We must be sure our lives are in compliance with God's word, we only want to hear at the end of our days "Well done, thou good and Faithful Servant".
