Mark 7:20-23 says And he said, That which cometh out of the man, that defileth the man.
Thefts, covetousness, wickedness, deceit, lasciviousness, an evil eye, blasphemy, pride, foolishness: All these evil things come from within, and defile the man.
Whatever we watch, goes in our hearts and what is in our hearts, comes out of us in conversation, attitudes and actions. If you take notice of the things you watch, see if any of these things are in it and make the choice to glorify God in what you are putting in your heart and the hearts of your family. Just like we can't eat junk food every day and have a healthy body, we can't fill our hearts with the dirty things of this world, and expect that we can be filled with God's spirit so that he can use us for his glory.
