The angel said to them, “Behold, I bring you good tidings of great joy which shall be to all the people; for there is born to you this day a savior, who is Christ the Lord.” (Luke 2:10)
The Gospel teaches that Christ was born, and that he died and suffered everything on our behalf, as is here declared by the angel. In these words you clearly see that he is born for us.
He does not simply say, Christ is born, but to you he is born. Neither does he say, I bring glad tidings, but to you I bring glad tidings of great joy. Furthermore, this joy was not to remain in Christ, but it shall be to all the people. This faith no condemned or wicked man has, nor can he have it. Christ has a pure, innocent, and holy birth. Man has an unclean, sinful, condemned birth; as David says (Psalms 51:5): “Behold, I was brought forth in iniquity; and in sin did my mother conceive me.” Nothing can help this unholy birth except the pure birth of Christ. For this purpose Christ willed to be born, that through him we might be born anew.
O, this is the great joy of which the angel speaks. This is the comfort and exceeding goodness of God that, if anyone believes this, he can boast of the treasure that Mary is his rightful mother, Christ his brother, and God his father. For these things actually occurred and are true, but we must believe. This is the principal thing and the principal treasure in every Gospel. Christ must above all things become our own and we become his. This is what is meant by Isaiah 9:6: “Unto us a child is born, unto us a son is given.” To you is born and given this child.
Therefore see to it that you do not treat the Gospel only as history, for that is only transient; neither regard it only as an example, for it is of no value without faith. Rather, see to it that you make this birth your own and that Christ be born in you. This will be the case if you believe, then you will repose in the lap of the virgin Mary and be her dear child. But you must exercise this faith and pray while you live; you cannot establish it too firmly. This is our foundation and inheritance, upon which good works must be built.
The Gospel does not merely teach about the history of Christ. No, it enables all who believe it to receive it as their own, which is the way the Gospel operates. Of what benefit would it be to me if Christ had been born a thousand times, and it would daily be sung into my ears in a most lovely manner, if I were never to hear that he was born for me and was to be my very own? If the voice gives forth this pleasant sound, even if it be in homely phrase, my heart listens with joy, for it is a lovely sound which penetrates the soul.
If Christ has indeed become your own, and you have by such faith been cleansed through him and have received your inheritance without any personal merit, it follows that you will do good works of Christ? Is it not true that they are good because they have been done for your benefit, for God’s sake, who commanded him to do the works in your behalf? In this then Christ was obedient to the father, in that he loved and served us.
Therefore since you have received enough and become rich, you have no other commandment than to serve Christ and render obedience to him. Direct your works that they may be of benefit to your neighbor, just as the works of Christ are of benefit to you. For this reason Jesus said at the Last Supper: “This is my commandment, that you love one another; even as I have loved you.” Here it is seen that he loved us and did everything for our benefit, in order that we may do the same, not to him, for he needs it not, but to our neighbor. This is his commandment, and this is our obedience. Christ helps us, so we in return help our neighbor, and all have enough.
Notice then how far off those are who expend their energies uniting good works with stone. Of what benefit is it to your neighbor if you build a church entirely out of gold? Of what benefit to him is the frequent ringing of great church bells? Of what benefit to him is the glitter and the ceremonies in the churches, the clergy’s robes, the sanctuary? Of what benefit to him are the many candles or the singing of vigils and liturgies? Do you think that God wants to be served with the sound of bells, the smoke of candles, and such fancies? He has commanded none of these, but if you see your neighbor going astray, sinning, or suffering in body or soul, you are to leave every thing else and at once help him in every way in your power and if you can do no more, help him with words of comfort and prayer. Thus has Christ done to you and given you an example for you to follow.
Here Jesus does what he says: “And the poor have good tidings preached to them,” and “Blessed are the poor in spirit; for theirs is the kingdom of Heaven.” (Matthew 11:5, 5:8) Here are no learned, no rich, no mighty ones for such people do not as a rule accept the Gospel. The Gospel is a heavenly treasure, which will not tolerate any other treasure, and will not agree with any earthly guest in the heart. Therefore whoever loves the one must let go the other, as Christ says, “You cannot serve God and mammon.” (Matthew 6:24)
This is shown by the shepherds in that they were in the field, under the canopy of Heaven, and not in houses, showing that they do not hold fast and cling to temporal things. And besides being in the fields by night, they are despised by and unknown to the world which sleeps in the night, and by day delights so to walk that it may be noticed; but the poor shepherds go about their work at night. They represent all the lowly who live in Earth, often despised and unnoticed but dwelling under the protection of Heaven; they eagerly desire the Gospel.
That there were shepherds means that no one is to hear the Gospel for himself alone, but every one is to tell it to others who are not acquainted with it. For he who believes for himself has enough and should endeavor to bring others to such faith and knowledge, so that one may be a shepherd of the other, to wait upon and lead him into the pasture of the Gospel in this world, during the nighttime of this earthly life. At first the shepherds were sore afraid because of the angel; for human nature is shocked when it first hears in the Gospel that all our works are nothing and are condemned before God, for it does not easily give up its prejudices and presumptions.
Therefore let us beware of all teaching that does not set forth Christ. What more would you know? What more do you need, if indeed you know Christ, as above set forth, if you walk by faith in God, and by love to your neighbor, doing to him as Christ has done to you. This is indeed the whole Scripture in its briefest form: that no more words or books are necessary, but only life and action.
Let everyone examine himself in the light of the Gospel and see how far he is from Christ, and what is the character of his faith and love. There are many who are enkindled with dreamy devotion, and when they hear of the poverty of Christ, they are almost angry with the citizens of Bethlehem. They denounce their blindness and ingratitude, and think, if they had been there, they would have shown the Lord and his mother a more kindly service, and would not have permitted them to be treated so miserably. But they do not look by their side to see how many of their fellow humans need their help, and which they ignore in their misery. Who is there upon Earth that has no poor, miserable, sick, erring ones around him? Why does he not exercise his love to those? Why does he not do to them as Christ has done to him?
