Whatever you do, work at it with all your heart, as working for the Lord

Colossian 3:18-4:6
Husbands, love your wives and do not be harsh with them.
Fathers, do not embitter(怨恨) your children, or they will become discouraged.
Slaves, obey your earthly masters in everything; but with sincerity of heart and reverence for the Lord. Whatever you do, work at it with all your heart, as working for the Lord, not for human masters, since you know that you will receive an inheritance from the Lord as a reward. 
Masters, provide your slaves with what is right and fair, because you know that you also have a Master in heaven.
Devote yourselves to prayer, being watchful and thankful.
Let your conversation be always full of grace, seasoned with salt, so that you may know how to answer everyone.
Why?
Let your conversation be always full of grace, seasoned with salt, so that you may know how to answer everyone. I need this.
Devote myself to prayer, I need to do more.
Being watchful and thankful: In prayer I need more watchful and thankful to devote myself.
Working for the Lord, doing everything as doing for the Lord. So I  can say the right word.
How?
Whatever you do, work at it with all your heart, as working for the Lord. Being watchful and thankful.
