The Bible teaches that slaves should be obedient to their masters. "Slaves, obey your earthly masters in everything; and do it, not only when their eye is on you and to win their favor, 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 men, since you know that you will receive an inheritance from the Lord as a reward. It is the Lord Christ you are serving." (Colossians 3:22-24)
Employees should be trustworthy. "Like the coolness of snow at harvest time is a trustworthy messenger to those who send him; he refreshes the spirit of his masters." (Proverbs 25:13)
The Bible sets high standards for the employee / employer relationship. "Teach slaves to be subject to their masters in everything, to try to please them, not to talk back to them, and not to steal from them, but to show that they can be fully trusted, so that in every way they will make the teaching about God our Savior attractive." (Titus 2:9-10)
Be diligent at work.
“Whatever you do, do well. For when you go to the grave, there will be no work or planning or knowledge or wisdom.” (Ecclesiastes 9:10).
Employees should make a habit of doing more than is expected from them. "If the God of my [Jacob’s] father, the God of Abraham and the Fear of Isaac, had not been with me, you would surely have sent me away empty-handed. But God has seen my hardship and the toil of my hands, and last night he rebuked you." (Genesis 31:42) Jacob worked hard even after several pay cuts. His diligence eventually paid off and his flocks began to multiply.
At many places in the Bible it teaches that we should be satisfied with our current employment conditions. "Then some soldiers asked him, "And what should we do?". He replied, "Don't extort money and don't accuse people falsely—be content with your pay." (Luke 3:14)
All believers should be happy with what they have. "Keep your lives free from the love of money and be content with what you have, because God has said, "Never will I leave you; never will I forsake you." (Hebrews 13:5)
Employees should submit to their employers, even to those who are strict. "Slaves, submit yourselves to your masters with all respect, not only to those who are good and considerate, but also to those who are harsh." (1 Peter 2:18)
Ambition at work. Some people spend a lot of their time at work chasing after a promotion or perhaps trying to get additional financial gain (earn a bonus/pay increase). This may require them working long hours – late at night or weekends. "What good is it for a man to gain the whole world, and yet lose or forfeit his very self?" (Luke 9:25)
Christian workers are to do their jobs with joyful attitudes and thankful hearts. ”So I concluded there is nothing better than to be happy and enjoy ourselves as long as we can.” (Ecclesiastes 3:12).
God expects Christians to enjoy their careers and the results of their hard work. “And people should eat and drink and enjoy the fruits of their labor, for these are gifts from God.” (Ecclesiastes 3:13).
The Christian career is blessed when God is allowed to work through the Christian to reach others. "Do you see any truly competent workers? They will serve kings rather than working for ordinary people.” (Proverbs 22:29).5
