To demonstrate a hypocritical lifestyle. Empty a can of Sprite and fill it full of Coke. As you begin talking, pour the contents of the “Sprite” into a clear glass. Ask the students if they have ever had the problem of getting something that is packaged wrong. Then, you can drive home the point that we tell people what we think we are, but we demonstrate who we really are inside. And, because we labeled ourselves incorrectly, people will be frustrated with us. Christians can be the greatest witness to the Gospel and Christ’s love, or they can be the greatest detractor from it.
