Our work should be marked by integrity. It's in the Bible, Ephesians 6:7, NIV. "Serve wholeheartedly, as if you were serving the Lord, not men."
Everything we do should honor Christ. It's in the Bible, Colossians 3:17, NIV. "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."
Everything we do should be done to the best of our abilities. It's in the Bible, Ecclesiastes 9:10, NIV. "Whatever your hand finds to do, do it with all your might, for in the grave, where you are going, there is neither working or planning nor knowledge nor wisdom."
