The words from Galatians (6:7) "Be not deceived" were the Golden Text for the Bible Lesson titled "Matter" one Sunday. While I was studying this lesson during the previous week I decided to focus my attention on understanding how one should think—what one should lean on, realize, and obey—in order not to be deceived.
As a result, I learned more of what it means that matter, error, or evil, is a belief of the human mind. The Bible reveals that good is God and that God's creation is purely good. I also saw that to gather the fruits of healing we must firmly and understandingly follow the teachings of Christ Jesus, be firm before the deceptive appearances of matter, have absolute faith in divine Mind (not doubt that Truth heals), and silence the arguments of error and erroneous human beliefs.
How useful these instructions were!
