Memory Verse
Carefully guard your thoughts, because they are the source of true life. Proverbs 4:23

Do you know what poison is? It’s stuff in your house that can really hurt you if you eat it or drink it. Usually, it’s marked with a scary symbol that tells you to stay away from it! Did you know that our thoughts can be poisonous to us? The Bible says that we should be on guard against allowing certain thoughts in our lives. See, our thoughts shape everything about us. So if we think wrong, we’ll act wrong. The Bible tells us there are 3 kinds of poisonous thoughts we need to keep out of our lives:

Poison #1: Being __________

Walking around being negative all the time isn’t good. It makes you sad, and it makes people around you sad. It’s poisonous to everyone.

Poison #2: Being __________

Have you ever been so scared that you could hardly sleep? And even when your parents told you not to worry, you still did. Fear is poison because it makes us doubt God. Just remember: God is always in control, no matter what.

Poison #3: Being _________

Do you ever get so angry that you want to hit somebody or hate somebody? That’s poison! It’s not just bad for the other person – it’s bad for you!
