Have you ever tricked yourself into believing something that wasn't true? Did Jesus really say that many people think they are following God when they are not? How can one determine that his faith is real? What will happen to those who come to the end and find out that they never were followers of Christ? This sermon finishes a long series on Jesus' Sermon on the Mount by warning of the dangers of self-deception regarding the genuineness of a one's own faith.
