The inspiration for this awesome design comes from a verse in Philippians 4. It talks about things which we should think about: whatever is lovely, whatever is admirable, whatever is true, etc. We often find our minds trailing off into strange places and thoughts that are opposite of these things, but Paul’s charge here is to reorient our thoughts to anything which is "praise worthy." Our thoughts should reflect our relationship with the Lord, and we should continue to keep our focus on Jesus because He is all these things.
