Complete Sermon - Trinity 18 - The Two Greatest Commandments - Christ Is David's Son And David's Lord
23. Hence, take to thyself this commandment: Thou shalt love the Lord thy God with all thy heart, and think upon it, contemplate it, and search what kind of a law it is; how far you are from fulfilling it, yea, how you have not yet even made a beginning to suffer and to do from the heart what God demands of you. It is pure hypocrisy, if anyone wants to creep into a hiding-place and think: Oh I will love God. Oh, how I do love him, he is my Father! How gracious he is to me! and the like. Yes, when God does our pleasure, then we can easily say such things; but when he sends misfortune and adversity, we no longer regard him as our God, nor as our Father.
24. True love to God does not act in this way, but in the heart it thinks and with the lips says: Lord God, I am thy creature; do with me as thou wilt; it matters not to me. I am ever thine, that I know; and if thou desirest, I will die this very hour or suffer any great misfortune; I will cheerfully do so from my heart. I will not regard my life, honor and goods and all I have, higher and greater than thy will, which shall be my pleasure all my days.
But you will never find a person who will constantly regulate himself according to this commandment; for the whole life you are living in the body, in the five senses, and whatever you do in your body, should all be so regulated as to be done to the glory of God, according to the regulations of this commandment, which saith, “Thou shalt love the Lord thy God with all thy heart, with all thy soul, with all thy mind.” As if Christ said: If you love God with all your heart, with all your soul, and with all your mind, then nothing will be lacking; you shall experience it in your daily life, namely: when everything you do, whether you wake or sleep, whether you labor or stand idle, whether you eat or drink, is directed and done out of love to God from the heart. In like manner your mind and thoughts will also be directed wholly and entirely to God, so that you will approve of nothing you are not certain is pleasing to God. Yea, where are those who do this?
25. And this part where he says, “With all thy mind,” argues powerfully against the writings and teachings of man, upon which he especially depends, and thinks thereby to obtain a merciful God and merit heaven.
Such imagination of the human reason draws us in a wonderful manner from this commandment, so that we do not love God with all the mind; as has been done hitherto, and is still done at the present day. For these priests and monks think nothing else than that God is moved by the mass and by other human inventions; but he abhors it and does not desire it, as is said in Isaiah 29:13: “In vain do they serve me, because they are teaching such doctrines which are only the commandments of men.” Matthew 15:8-9. The commandment here requires you to consider nothing good that is against God and against everything he has commanded or forbidden. It thus requires, you to give yourself wholly and entirely to him in all your life and conduct.
26. From this you can conclude, there is no human being who is not condemned, inasmuch as no one has kept this commandment, and God wants everyone to keep it. There we stand in the midst of fear and distress, unable to help ourselves, and the first knowledge of the law is, that we see our human nature is unable to keep the law; for it wants the heart, and if it is not done with the heart, it avails nothing before God. You may indeed do the works outwardly, but God is not thus satisfied, when they are not done from the heart, out of love; and this is never done except man is born anew through the Holy Spirit. Therefore God aims to accomplish through the law nothing more than that we should in this way be forced to acknowledge our inability, frailty and disease, and that with our best efforts we are unable to fulfill a letter of the law. When you realize this, the law has accomplished its work. This is what Paul means when he says in Romans 3:20, “Through the law is the knowledge of sin.”
27. From this it appears clearly that we are all alike, and are one in the inner wickedness of the heart, which the law reveals, when we look into it rightly. Therefore we might well say, If one is good, then all are good.
Therefore no one should accuse another. It is indeed true that in public and gross sins there sticks a deeper sin; but the heart is alike bad, unless it be renewed by the Holy Ghost. But what shall I do when I once recognize my sin? What does it profit me? It helps me very much, for when I have come thus far, I am not far from the kingdom; as Christ says to a scribe in Mark 12:34, who also knew that the works of the law were nothing without love.
28. But what shall we do to get rid of our bad conscience? Here follows now the other part of this Gospel, namely, who Christ is and what we can expect of him. From him we must receive and secure freedom from a wicked conscience, or we shall remain in our sins eternally, because for this purpose is Christ made known and given by the Father, in order that he might deliver us from sin, death, from a wicked conscience, and from the law.
29. We have now heard what the law is, and how through the law we come to the knowledge of sin; but this is not enough, another has a work to do here, whose name is Christ Jesus; although the first, the law, must indeed remain; yea, it is necessary. For if I have no sense of my sins, I will never inquire for Christ; as the Pharisees and scribes do here, who thought they had done everything the law commanded and were ready to do yet more; but of Christ they knew nothing. Therefore, first of all, when the law is known and sin revealed through the law, it is then necessary that we know who Christ is; otherwise the knowledge of sin profits us nothing.
30. But the law is known, when I learn from it that I am condemned, and see that there is neither hope nor comfort anywhere for me, and I cannot even help myself, but must have another one to deliver me. Then it is time that I look around for him who can help, and he is Christ Jesus, who for this purpose became man, and became like unto us, in order that he might help us out of the mire into which we are fallen. He loved God with all his heart and his neighbor as himself, and submitted his will to the will of his Father, fulfilled the law in every respect; this I could not do and yet I was required to do it. Therefore, he accepts him; and that which he fulfilled in the law, he offers me. He freely gives me his life with all his works, so that I can appropriate them to myself as a possession that is my own and is bestowed upon me as a free gift. He delivers us from the law, for when the law says, Love God with all thy heart, and thy neighbor as thyself, or thou wilt be damned, then I say, I cannot do it. Then Christ says: Come to me, take me and cling to me by faith; then you shall be rid of the law.
31. Now this is accomplished in the following manner: Christ has through his death secured for us the Holy Spirit; and he fulfills the law in us, and not we. For that Spirit, whom God sends into your heart for the sake of his Son, makes an entirely new man out of you, who does with joy and love from the heart everything the law requires, which before would have been impossible for you to do. This new man despises the present life, and desires to die, rejoices in all adversity, and submits himself wholly and entirely to the will of God. Whatever God does with him, is well pleasing to him. This Spirit you cannot merit yourself, but Christ has secured and merited it. When I believe from the heart that Christ did this for me, I receive also the same Holy Spirit that makes me an entirely new man. Then everything God commands is sweet, lovely and agreeable, and I do everything he desires of me; not in my own strength, but by the strength of him that is in me, as Paul says in Philippians, 4:13: “I can do all things through Christ that strengtheneth me.”
32. But you must take heed, that you do not undertake to secure this faith in Jesus Christ by your own works or power, or that you think lightly about this matter; for it is impossible for the natural man; but the Holy Spirit must do it. Therefore beware of the preachers of self-righteousness, who simply blabber and say: We must do good works in order to be saved.
But we say that faith alone is sufficient to this end. Our good works are for another purpose, namely, to prove our faith, as you have already frequently heard from me.
33. Now this is the purpose of the question the Lord put to the Pharisees:
What think ye of Christ; who is he and whose Son is he? But their answer, in that they say, He is the son of David, the Lord rejects and obscures their answer and refers to a passage from the Psalm, in order to leave them in doubt; so that no one is able to answer him a word.
34. However, when David calls Christ his Lord, in that he says in Psalm 110:1, “But the lord said unto my Lord, ‘Sit thou on my right hand until I make thine enemies thy footstool,’” it is to be understood that David speaks of him both as God and man, for according to the flesh alone he was the son of David. Paul also joins these two when he says in Romans 1:1-4: “I am called to be an apostle, separated unto the Gospel of God, which he promised afore through his prophets in the Holy Scriptures, concerning his Son, who was born of the seed of David according to the flesh; who was declared to be the Son of God with power, according to the Spirit of holiness, by the resurrection from the dead.” But it is something to know that Christ is Lord; for this has might and power and is especially comforting in the time of affliction. But concerning this I have said more elsewhere and will therefore now close, and pray God for grace.
