A favorite verse:
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.
Reason:
Doing so brings peace and well-being. - Bible Verses from the King of kings' Bible - #19 by NancyDrewberry
