1. Renew your mind in the Word of God.
2. Captivate thoughts that don't line up with the Word of God.
3. Commit your works unto the Lord and your thoughts will be established.
4. FINALLY: Philippians 4:8. "For the rest, brethren, whatever is true, whatever is worthy of reverence and is honorable and seemly, whatever is just, whatever is pure, whatever is lovely and lovable, whatever is kind and winsome and gracious, if there is any virtue and excellence, if there is anything worthy of praise, think on and weigh and take account of these things [fix your minds on them]."
