Thank you JonHenry. When I saw this thread had surfaced again, that is exactly what I was going to mention. Here it is in context, folks:
Finally, brothers, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable -- if anything is excellent or praiseworthy -- think about such things.
Philippians 4:8
consider also Colossians 3:15-17:
Let the peace of Christ rule in yourhearts, since as members of one body you were called to peace. And be thankful. Let the word of Christ dwell in you richly as you teach and admonish one another with all wisdom, and as you sing psalms, hymns and spiritual songs with gratitude in your hearts to God. And WHATEVER YOU DO, WHETHER IN WORD OR DEED, DO IT ALL IN THE NAME OF THE LORD JESUS, giving thanks to God the Father through him.
Or, a little earlier in that same chapter:
Since, then, you have been raised with Christ, set your hearts on things above, where Christ is seated at the right hand of God. Set your minds on things above, not on earthly things.
And it is also written that every thought should be taken captive to Christ.
