"Slaves obey in everything those who are your earthly masters, not by way of eye-service as people-pleasers but with sincerity of heart fearing the Lord. Whatever you do, work heartily as for the Lord and not for men, knowing that from the Lord you will receive the inheritance as your reward You are serving the Lord Christ."
The key for the Christian is to remember who is ultimately our Boss. Whatever we are doing - and the slave in this passage was probably doing the really menial jobs - it is Christ we are serving. We are called to work hard at everything because our ultimate reward is in Heaven not on Earth. What if we hate it? What if we struggle? Remember - it is Christ we are serving and our reward is in Heaven.
