We are all familiar with the old saying, “you are what you eat”. Meaning that what we put in our bodies can have a great affect on our physical health. In a similar way, what we put into our minds has a great affect on our spiritual health. Proverbs 4:23 warns us to, “Keep your heart with all diligence, for out of it spring the issues of life”, because, as we are told in Proverbs 23:7, “as he thinks in his heart, so is he”.We are what we think. The problem is that what we think is influenced largely by what we see and hear. In 1 Corinthians 15:33 the Apostle Paul tells us that, “evil company corrupts good habits”. The people we have around us will influence our habits of thought. In this day and age we also are influenced by the things we see and hear in the media. We must be careful to avoid as much as possible those things that may negatively influence our habits of thought. Instead we should work to positively influence our habits of thought by spending more time in study of, and meditation on, God’s word. “He who walks with wise men will be wise, but the companion of fools will be destroyed”. (Proverbs 13:20). As Paul tells us in Philippians 4:8, “Finally, brethren, whatever things are true, whatever things are noble, whatever things are just, whatever things are pure, whatever things are lovely, whatever things are of good report, if there is any virtue and if there is anything praiseworthy—meditate on these things.”
