Let's take a look at Nemoria arizonaria. I'm sure you were just talking about him at lunch, right? It's a caterpillar! That's what a lot of us know him as. Now, some caterpillars are born in the spring and some are born in the summer. The spring bunch I understand, eat oak catkins. That's the dangling flowers on an oak tree. And within days, guess what? They look as fuzzy as their meal was that they ate just a few days ago. Oh, let's take the summer bunch now. They eat smooth leaves because that's what's out then. Would you believe it? They become smooth caterpillars. It's amazing! Caterpillars exemplify that old adage, "You are what you eat." They literally are. That doesn't mean you're going to begin to look like your lunch I hope. That's a scary thought. But in another way, the caterpillar dynamic is happening to you.

I'm Ron Hutchcraft and I want to have A Word With You today about "Healthy Diet, Healthy Heart."

Our word for today from the Word of God comes from Philippians 4:8. "Finally, brothers, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable. If anything is excellent or praiseworthy, think about such things." That's dietary advice. You think it's not about eating? Well it is. It's about what you consume mentally and spiritually; what you allow to come into your mind, your ears, your eyes, your heart. And if it isn't noble, and true, and right, and pure, and lovely, and admirable, you've got no business listening to it. You have no business dining on it mentally.

The Bible says, "As a man thinks in his heart so is he." You are what you eat. That's why Proverbs 4:23 says, "Guard your heart. Be careful what you let in there; it's the wellspring of life." Your mind is being programmed and shaped even today by what you hear, what you watch, what you laugh at, and your music. The subtle thing is you don't feel like anything's happening. You don't say, "Oh, I am now being programmed. I am now being influenced." You don't know it.

But input is what creates thoughts, and thoughts become fantasies and attitudes. And those attitudes eventually become actions. It's too late then. You can't stop this process. You can't feel it happening, and you can't stop it any more than a caterpillar can say, "I don't want to become bumpy like what I ate." Or, "smooth like what I ate."

You keep tuning in to depressing input, and you're going to start to feel a darkness growing inside of you. You keep fueling yourself with bad news about a certain person and all the things that are wrong about them, and you're going to find a growing bitterness and criticism in your spirit. You keep letting in sexually stimulating images, and increasingly it will affect how you view the opposite sex and your own sexuality.

See, the media is a lot more than entertainment. It's ideas and it's values wrapped up in bright attractive packages. I've decided I have to fight sin at the door. James 1:15 is so revealing, "After desire has conceived it gives birth to sin, and sin when it is full grown gives birth to death." You've got to fight it as a desire. Your most important choices are not so much about your actions; they're about your input. Actions all come from what you eat mentally.

For caterpillars and for Christians, diet is destiny.
