A Sermon on Deuteronomy 5:32-6:25 for Matins at St. Peter Indy

Note: This sermon was preached before the Confessions Study held on the 3rd Thursday of every month at St. Peter Lutheran Church, Indianapolis, IN. The sermon text comes from the daily lectionary found within Rev. Peter Bender’s Lutheran Catechesis.

Grace, mercy, and peace be unto you from God our Father and our Lord and Savior Jesus Christ. Amen.

“And you shall guard to do all which YHWH your God commands you. You shall not turn to the right or to the left. In all the words which YHWH your God commands you, you shall walk in order that you live and in order that it be good with you, and in order that you may prolong you days on the earth which you will take possession of.” (Dt. 5:31-32My translation)

Those words probably sounded pretty good to the people of Israel when Moses spoke these words to them again. You and I know that this is part of the Mosaic Covenant. All the words which the Lord speaks here to Israel through Moses are contingent upon the works of the people. “You shall observe.” “You must observe every word of the Lord’s commands.” “If you want to live, to truly live, then you must hold to the commands given.” Some people might like their odds with such commands. But you and I both know how Israel fared under such a burden. Peter speaks about the burdens in Acts. The Law is a yoke that no one is able to bear by their own strength. Yet, we have been given these words to live by. So what do we do with them?

Perhaps it’s best we go back to the original context of the covenant. The Lord God heard the groans and the cries of His people Israel. They had been under the burden of the Egyptians, and the Lord God, had promised even further back that He would remember Abraham’s descendants in Egypt and that He would give to them the Land promised to Abraham. The Lord remembered, and He knew what He would do to bring them salvation. The Children of Israel were not perfect before His act of salvation. But instead, the Lord God acted in love and in accordance with His promise made so many years before to Abraham. He brought Israel up out of Egypt by His mighty Right Hand. He bared His arm in triumph over Pharaoh and Egypt. And it is after this act of deliverance that the Lord speaks to Israel at Sinai. Now the Law was already on their hearts, but now at Sinai, the Lord God clarifies how He would continue to bring about the promise He had made to Abraham and to Adam and Eve. Israel, the children of Abraham, Isaac, and Jacob, would be a kingdom of priests. They were to be beacons of light; they were to be different from the world because they knew their saving God. They knew His name, and they were to call upon Him. They were to teach and preach to the rest of the nations about their God, the creator of Heaven and Earth, and the one who had redeemed them from the clutches of Egypt, that house of slavery and death.

Like Luther’s explanation of the First Article, God acted first in love. He created, sustained, and defended the children of Israel, so having experienced all that, then it would be Israel’s duty to thank, praise, serve, and obey the Lord their God. Not because Israel was afraid of Him, but because Israel did not wish to “let God down” similar to how a son does not desire to do a crummy mowing job and thus lose the respect of his father. No, the son desires to do good because he knows his father loves him, and he does not want to let him down. Is this not what Israel is called to do as well? To desire to do good because they were God’s chosen possession and instrument to prepare the rest of the nations for the blessing that was to come from the Messiah who was to be born from their line?

But what happened? Rebellion.

Not even 60 days after all the events that transpired to bring Israel from Egypt to Sinai, upon receiving the original stone tablets with all the words of the Law upon it, Israel chased after idolatry. The golden calf was set up and worshipped as if the Lord was a calf. This flew in the face of the command to be different from the nations. Hear O Israel, the Lord our God, the Lord is One. And you Shall love the your God with all your heart and with all your soul and with your might.” So much for teaching this to their sons.

But are we, in this generation, any different? How many of our own people fail to teach the word of God to their own children? Have we fallen into the same type of holes? Are we teaching our children well or are we letting the world catechize them? Our children are being catechized one way or the other, may God have mercy on us all.

We have the duty to teach and proclaim the excellencies of Him who brought out of our darkness of sin and eternal death and into His marvelous light. You and I get to do the most amazing job in the world. We get to do it not simply for our children but for the people entrusted to our care in our congregations. We get to speak God’s Word and have it on our mouths as we sit in our houses, we walk by the way, and when we rise up and lie down, as well as our pulpits.

We cannot take this opportunity for granted and we cannot assume that our own children will just grow up and remain Christian because of living with a pastor as a father. There is too much evidence to the contrary. Our Lord tells us to teach, and so we ought to do that.

And if you teach by your own strength, you might do well for a while. But if you teach yet are not being taught and fed yourself, you will be no better than Israel of Old. Your bones will dry up, and you will be spiritless. You and I cannot do teach or even believe in what God has done for us in love by our own reason or strength. God did not send His son for us because of anything you or I have done to earn such a gracious visit, but He did it out of His own compassion and love. He acted first. Be fed His love. Know for yourself who this Lord and God is, know that He has called you His own possession. You are a chosen one. You are made Holy by Him, and you have been granted to hear the words of eternal life as well as believe them. That word first preached to your own ears has gone from the ear to the heart and now from the heart to the mouth so that you might do that which our Lord commands now. You and I are no longer under the curse of the Law, but we are justified on account of the One who has been sent, Jesus Christ, the promised Messiah. It is through Him and Him alone that w are blessed and made new. No longer is the Law of God only there serving to accuse us, but it is there showing us what children of God do because we are God’s children. This is how we live. We live by God’s Word. We live by faith trusting that Christ has come to save. And He grants us strength so that we might live in righteousness and purity before God even now as we receive from Him the forgiveness of sins by the preaching of His and the administration of His Sacraments.

You and I get to know the Lord as the Lord who has created, sustains, redeems, and sanctifies us. And we get to teach this to our children. May we be blessed in the task to raise up our physical children as well as our spiritual children in this holy faith. Let us not lose hope in the midst of this endeavor but cling to the promises of Christ our Lord, who is ever with us in the task. It He who gives the Word. It is He who gives the Growth. It is He who brings His Harvest home. You and I are blessed to be part of the work. God be praised now and ever for what He has done, having sent the only begotten One into the world to make a people for Himself. May we never forget or lose sight of this good and gracious gift which we get to proclaim. The message of Christ Jesus who came to seek and redeem us lost and condemned souls.

In the Holy Name of Jesus. Amen.
