One of the characteristics of biblical leaders is learning to think about the right things.
Two major portals are the gateway to our minds: eyes and ears. While all the senses play a part, these two are primary. Sadly, we often fail to recognize the influence of what we see and hear on our thinking.
The type of language in movies or television shows, pornographic nature of advertisements or programs, jokes, and the locations we visit are only four ways we are influenced through the eyes and ears.
Paul was specific about the areas described in Philippians 4:8. The key is understanding the imperative need for our minds to dwell on these things.
Doing so requires work. We must be proactive in the way we approach the influences on our mind: entertainment, friends and activities.
Is our leadership influence worth having our minds filled with negativity, filth, and horror for a little entertainment?
We are in the world, but not of the world. We are to influence the world for Christ, the Light of the world, not to be influenced by the world.
