Christ employs this parable to teach us the difference between His kingdom and the kingdom of this world. Affairs in the former differ entirely from those in the latter, in which there is an inequality among persons. Our Gospel has nothing to do with this existing inequality in the world, where the master has many possessions and the servant who labors for him none, or but few; the parable simply refers to the kingdom of God, and teaches us that in it all inequality is abolished, that everything is common property there, and that one shall have as much, and be esteemed as much, as the other. In our daily life, however, there will always be a marked distinction among men on account of their various pursuits. The peasant will have a mode of life different from that of the citizen, and the prince from that of the nobleman. In these matters there is inequality everywhere, and so it must remain. But in the kingdom of Christ it is otherwise; there is no distinction there among believers; they are all alike, whether they be kings, princes, governors, masters or servants. All have the same Baptism, Gospel, Faith, Sacrament, the same Christ and God. They all attend divine worship in perfect equality; the servant, the mechanic and the peasant hear the same Word as the mightiest lord. The Baptism wherewith I was baptized belongs to every other child, whether rich or poor. Magdalene and the malefactor on the cross have the same faith which St. Peter and St. Paul had; yea, the selfsame faith which you or I have, if we are Christians. All sinners, if converted, have the same God and Christ whom John the Baptist had. There is no difference here, though one may by far excel the other in his station in life, in his calling, or in his talents. (Luther’s House Postil, Sermon for Septuagesima, Volume 1, p. 210-211)

Such kindness must prompt us in all our troubles to come unto Him for help, and to place our entire confidence in Him. But more than this: it ought to prompt us to exercise similar kindness and love towards our fellow-men, with the sole intention to do the will of God and to promote the welfare of our neighbor. Christ seeks neither honor nor reward in rendering assistance; He has but this in view, that man may be relieved from woe and suffering, that the glory of God may be enhanced and His will accomplished.

We do not serve God if we are kind to others merely because we expect a similar return from them. Such a spirit would be selfish. If we wish to serve God and our brother aright, we must not look to our own interest, but only to the existing want. We must bear in mind that it is God’s will and command to assist our fellow-man in his time of need, though we are aware that we gain not even a farthing by it, or perhaps naught but ingratitude; as Christ Himself experienced when He cleansed ten lepers, nine of whom forgot to thank Him, and only one returned with a grateful heart. Christ foresaw this base ingratitude, and yet He helps them when they ask, committing the rest to God in heaven. (Luther’s House Postil, Sermon for the 3^rd Sunday after Epiphany, Volume 1, p. 185-186)
