Masters have a corresponding duty to their slaves and are not free because of their earthly status to behave as they like. Paul says, ‘do the same things to them’, obviously not meaning that masters are to obey or serve their slaves but that they are have the same awareness that they are subject to the will of God and, out of the same reverence for Christ, they are to treat their slaves as fellow human beings to whom they owe a debt of benevolence, fairness and even respect.
The Christian master or employer is to remember that, if he is a master on earth, he has a Master over him to whom he too must give account. This account includes his conduct towards his slave or employees. He is not at liberty to behave cruelly or unjustly as if he had absolute rights over another human being, but is to remember that both he and his slave are made in the image of God. There is no partiality with God, and therefore God does not regard the master with the awe that other human beings might regard him. Each of us is treated by God as answerable to him, and he will not show special favour to one just because he is a master on earth. How vastly higher than all his creatures God is! How then can we expect favouritism from him that would overlook our faults on the basis of our superior earthly status? Rather, there should be a humility about us as masters, which means that to a great extent we ignore the privileges that our earthly circumstances have allotted to us, and remember that we are all equal before God. This does not stop us functioning in the roles that we have in society, but it tempers our natural pride and haughtiness so that whatever powers we have do not go to our heads.
