Colossians 3:23,24

Whatever you do, do it heartily, as to the Lord and not to men, knowing that from the Lord you will receive the reward of inheritance; for you serve the Lord Christ.

If we are Christians, we serve the Lord Christ.  Serving Christ and our relationship with Him should increase our confidence and motivations to be prosperous in our daily lives.  The accolades of the world cannot compare to the rewards we have in Heaven.  We are motivated to do good because we serve a good God and represent Him here on earth.
