Object Lesson

Do you like my t-shirt? It is brand new and perfectly clean! This is just like our heart when Jesus forgives us. He makes us perfectly clean inside. He removes all of our sin and stains.

Now what do you think would happen if I saw my friend and he had just finished painting his house and working on his car and he was all filthy. (Take out the dirty shirt.) What do you think would happen if I have him a hug? Do you think that all of my clean would rub off on him? You don’t? Why not?

(Take the dirty shirt and rub it against your clean shirt.)

My clean shirt didn’t make this dirty shirt clean did it? The dirty shirt made my clean on dirty!

The Bible asks us in 2 Corinthians 6:14 what fellowship light can have with darkness and warns us inĀ 2 Corinthians 6:17 to not touch something unclean! Why? Because usually our good does not rub off on them but their bad habits rub off on us.

If you have a best friend that always swears or lies or steals you may start doing that soon too! We will often pick up other people’s bad habits.
We should not totally isolate ourselves because God wants is to share our faith, but we have to be careful because if we are best friends with someone who is far from God they will often pull us away from God too.
