There are tons of areas in life where we have to make choices. One of the critical areas (in my opinion) is what we watch and listen to. Why? Because the things we take into our lives affect our thinking and shape our beliefs and behaviors. So why does that matter?
I belong to God and my goal is to honor him: "You are not your own, for you were bought with a price. So glorify God in your body" (1 Cor 6:19b-20). How do I glorify God in my body?
"I appeal to you therefore brothers, by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God which is your spiritual worship. Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect" (Rom 12:1-2).
I worship God when I fully surrender my life - my body - to God, not following the world's ways, but seeking mind/thinking transformation from God. Then I can ask God: What do you want me to look at, think about, do, etc.?
He's already given answers to those questions in the Bible. He makes it pretty clear where our mind should be in Philippians 4:8:
"Finally brothers, whatever is true, whatever is honorable, whatever is just, whatever if pure, whatever is lovely, whatever is commendable, if there is any excellence, if there is anything worthy of praise, think about these things."
The things we look at and think about do affect our lives, directing us closer to or further from God. When I watch or dwell on unwholesome things, I'm indulging my fleshly desires and not surrendering to God's leading.
"Above all else, guard your heart, for it is the wellspring of life" (Prov 4:23).
For further reflection, read Ephesians 4:17-5:16, and Colossians 3:1-10.
