Philippians 4:8 Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things.
How we think determines how we live our lives. As believers, we are to see that our minds are in love with Jesus. Truth, honesty, justice, purity, lovely, and of good report are a picture of the Word of God.
If we fill our minds with the Words of God, there will be no room for evil or worry or fear. There will be no room for vengeance, confusion and trouble. A mind filled with and led by the Word of God is a stable mind.
