Colossians 3:22-25

22 Slaves, obey your earthly masters in everything, not only while being watched and in order to please them, but wholeheartedly, fearing the Lord.
23 Whatever your task, put yourselves into it, as done for the Lord and not for your masters,
24 since you know that from the Lord you will receive the inheritance as your reward; you serve the Lord Christ.
25 For the wrongdoer will be paid back for whatever wrong has been done, and there is no partiality.
