The duty of servants is summed up in one word, obedience. The servants of old were generally slaves. The apostles were to teach servants and masters their duties, in doing which evils would be lessened, till slavery should be rooted out by the influence of Christianity. Servants are to reverence those over them. They are to be sincere; not pretending obedience when they mean to disobey, but serving faithfully. And they must serve their masters not only when their master's eye is upon them; but must be strict in the discharge of their duty, when he is absent and out of the way. Steady regard to the Lord Jesus Christ will make men faithful and sincere in every station, not grudgingly or by constraint, but from a principle of love to the masters and their concerns. This makes service easy to them, pleasing to their masters, and acceptable to the Lord Christ. God will reward even the meanest drudgery done from a sense of duty, and with a view to glorify him. Here is the duty of masters. Act after the same manner. Be just to servants, as you expect they should be to you; show the like good-will and concern for them, and be careful herein to approve yourselves to God. Be not tyrannical and overbearing. You have a Master to obey, and you and they are but fellow-servants in respect to Christ Jesus. If masters and servants would consider their duties to God, and the account they must shortly give to him, they would be more mindful of their duty to each other, and thus families would be more orderly and happy.
22 Servants, obey in all things your masters according to the flesh; not with eyeservice, as menpleasers; but in singleness of heart, fearing God:
English Standard Version
22 Slaves,Or Servants; Greek Bondservants obey in everything those who are your earthly masters,Or your masters according to the flesh not by way of eye-service, as people-pleasers, but with sincerity of heart, fearing the Lord.
22 Servants, do what you're told by your earthly masters. And don't just do the minimum that will get you by. Do your best.
New King James Version
22 Bondservants, obey in all things your masters according to the flesh, not with eyeservice, as men-pleasers, but in sincerity of heart, fearing God.
New Living Translation
22 Slaves, obey your earthly masters in everything you do. Try to please them all the time, not just when they are watching you. Serve them sincerely because of your reverent fear of the Lord.
The epistles most taken up in displaying the glory of the Divine grace, and magnifying the Lord Jesus, are the most particular in pressing the duties of the Christian life. We must never separate the privileges and duties of the gospel. Submission is the duty of wives. But it is submission, not to a severe lord or stern tyrant, but to her own husband, who is engaged to affectionate duty. And husbands must love their wives with tender and faithful affection. Dutiful children are the most likely to prosper. And parents must be tender, as well as children obedient. Servants are to do their duty, and obey their masters' commands, in all things consistent with duty to God their heavenly Master. They must be both just and diligent; without selfish designs, or hypocrisy and disguise. Those who fear God, will be just and faithful when from under their master's eye, because they know they are under the eye of God. And do all with diligence, not idly and slothfully; cheerfully, not discontented at the providence of God which put them in that relation. And for servants' encouragement, let them know, that in serving their masters according to the command of Christ, they serve Christ, and he will give them a glorious reward at last. But, on the other hand, he who doeth wrong, shall receive for the wrong which he hath done. God will punish the unjust, as well as reward the faithful servant; and the same if masters wrong their servants. For the righteous Judge of the earth will deal justly between master and servant. Both will stand upon a level at his tribunal. How happy would true religion make the world, if it every where prevailed, influenced every state of things, and every relation of life! But the profession of those persons who are regardless of duties, and give just cause for complaint to those they are connected with, deceives themselves, as well as brings reproach on the gospel.
