The Blind Spots of Deception

How often is our mind mislead? All of us are familiar with "blindspots" in our cars. Sometimes we have wrecks because of those blindspots. This applies to our lives as well. Deception can wreck your life, your marriage, your relationship with God, your work, your fellowship with others. Who was first deceived in the Bible? Deception is the "blindspot". Truth is the "spot remover". Deception has a companion called "pride". They travel together. What are some signs I am deceived? What do I do about it?
