This is really good advice even if you arent christian.

There is so much trashy garbage produced and promoted by hollywood, the music industry, gaming, internet moguls.

Sometimes I think well this movie is pretty degenerate but I can handle it because Im an adult. It wont damage my mind

But it can. People dont acquire mental superpowers when the become 18 or 21. We can all be corrupted at anytime by the devious Enemy. And we can be demoralized as well. Question everything you put in to your mind.

You transform what you eat into something else. Emotions, Ideas, become transformed by the alchemy of the human soul. The catterpillar becomes the butterfly. Impressions are changed into will, ideas are changed into plans. We are not what we eat -- we use what we eat to become greater.
