Great reminder...
Colossians 3:23-24Complete Jewish Bible
Whatever work you do, put yourself into it, as those who are serving not merely other people, but the Lord. Remember that as your reward, you will receive the inheritance from the Lord. You are slaving for the Lord, for the Messiah.
It is so amazing how you feel good when you get things done. It is like we are hardwired to accomplish things. I live it.
