Objects needed:
carrot
egg
Lesson
Here is an object lesson idea emailed to me from my friend Brent Anderson, a former Seminary teacher:
"I took in a carrot and an egg. I asked [the students] what happened when they are boiled. One turns soft and the other turns hard even though the same thing happened to them. Same thing with trials: they can either make us hard or soft depending on how we choose to respond."
