Special Thanks to Carolee Radline for this great lesson
Could I explain an object lesson that you could use? Show various protective objects like a thimble, ear plugs, rubber gloves, eyeglass guards, knee pads,... Ask what they are and what they're used for. Yes, they're all used to help protect parts of you. Now, here's a question for you--Is there anything out there to protect your mind and your heart? That is your thoughts & ideas and your feelings? (or spirit and soul) It's hard to protect your mind/spirit because lots of the TV shows, movies, songs, books, & magazines, & even people around us try to make us think wrong thoughts. It's hard to protect our heart/soul because people hurt our feelings & make us feel bad. You'll never be successful at guarding your heart & mind unless you first have invited Jesus into you heart & realize God is the source of all truth & righteousness. And then begin to read His word and obey Him. What God commands us to do is for our protection because He loves us.
