Illusion is defined as an "erroneous perception of reality." Illusions can be fatal. If I view water in the canal as drinking water, I could die. Most dangerous of all illusions is spiritual. Sin is described by the Bible as one that clouds our ability to see right and wrong. Jeremiah refers to it as self deception: "The heart is deceitful above all things, . . . who can know it?" (Jeremiah 17:9). In Malachi's time, people were saying, ""Everyone who does evil is good in the sight of the Lord, and He delights in them" (2:17). They were not seeing things as God sees them. As we depend on God's Spirit and obey His Word, illusions are replaced by reality and truth. Many times, suffering and pain have a way of ridding ourselves of illusion and falseness in our hearts.
