Jesus warns us: out of the abundance of the heart, the mouth speaks. (Luke 6:45) Are you tired of the words coming out of your mouth? Start looking at what you are putting into your heart.
The movies, music, and books you read have power in your life. The media you consume influence you. The friends you keep will impact the person you become. At the end of the day we can ask several questions:
1. Does this honor Jesus?
2. Is this good for my mind?
3. Will this build me up or those I love?
And now, dear brothers and sisters, one final thing. Fix your thoughts on what is true, and honorable, and right, and pure, and lovely, and admirable. Think about things that are excellent and worthy of praise.
