Rev. Dr. Ryan Tietz, Associate Professor of Exegetical Theology and Dean of Students at Concordia Theological Seminary in Ft. Wayne, IN, joins host Rev. Timothy Appel to study Deuteronomy 5:22-33.

Moses recounts what happened after the LORD gave the Decalogue. He highlights the importance of the event by reminding Israel of the “thick darkness” on the mountain. This connects the theophany at Sinai to the day of the LORD when He sets all things right. The fact that the Decalogue was written further underscores its significance. Through the event, the people of Israel saw God’s grace in speaking to them, while at the same time recognizing their need for a mediator to continue to hear His Word. The LORD commended their request and appointed Moses to do so, a foreshadowing of our final mediator, Jesus Christ. With that historical background, Moses encourages the people now to walk in the way that the LORD has given them.

“The Law of God is Good and Wise” is a series on Sharper Iron that goes through the book of Deuteronomy. Though Moses’ lengthy sermons in Deuteronomy may be tempting to skip, this influential book is essential reading for Christians. As Moses strengthened Israel on the plains of Moab before the people entered the Promised Land, so the book of Deuteronomy still strengthens the Church as we prepare to enter the Resurrection with Christ, the Prophet greater than Moses.

Sharper Iron, hosted by Rev. Timothy Appel, looks at the text of Holy Scripture both in its broad context and its narrow detail, all for the sake of proclaiming Christ crucified and risen for sinners. Two pastors engage with God’s Word to sharpen not only their own faith and knowledge, but the faith and knowledge of all who listen.

Deuteronomy 5:22-33

22 “These words the Lord spoke to all your assembly at the mountain out of the midst of the fire, the cloud, and the thick darkness, with a loud voice; and he added no more. And he wrote them on two tablets of stone and gave them to me. 23 And as soon as you heard the voice out of the midst of the darkness, while the mountain was burning with fire, you came near to me, all the heads of your tribes, and your elders. 24 And you said, ‘Behold, the Lord our God has shown us his glory and greatness, and we have heard his voice out of the midst of the fire. This day we have seen God speak with man, and man still live. 25 Now therefore why should we die? For this great fire will consume us. If we hear the voice of the Lord our God any more, we shall die. 26 For who is there of all flesh, that has heard the voice of the living God speaking out of the midst of fire as we have, and has still lived? 27 Go near and hear all that the Lord our God will say, and speak to us all that the Lord our God will speak to you, and we will hear and do it.’

28 “And the Lord heard your words, when you spoke to me. And the Lord said to me, ‘I have heard the words of this people, which they have spoken to you. They are right in all that they have spoken. 29 Oh that they had such a heart as this always, to fear me and to keep all my commandments, that it might go well with them and with their descendants[a] forever! 30 Go and say to them, “Return to your tents.” 31 But you, stand here by me, and I will tell you the whole commandment and the statutes and the rules that you shall teach them, that they may do them in the land that I am giving them to possess.’ 32 You shall be careful therefore to do as the Lord your God has commanded you. You shall not turn aside to the right hand or to the left. 33 You shall walk in all the way that the Lord your God has commanded you, that you may live, and that it may go well with you, and that you may live long in the land that you shall possess.
