Grace, mercy, and peace to you from God our Father, and from our Lord and Savior, Jesus Christ, amen. The text for the sermon is the Old Testament, which was read earlier.
You get it, don’t you? You see the big picture, right? It should be obvious to everyone, and yet it is not. Isaiah doesn’t mince words in our text for today. He begins by saying, “Do you not know? Do you not hear? Has it not been told you from the beginning? Have you not understood from the foundations of the earth?” Imagine what that would sound like today: “Have you not heard from the beginning? Have you not understood even though it has been sufficiently shown to you? Now you should know it. How are you going to excuse yourselves for your errors?” Plain preaching and teaching has been set forward for God’s people, and it’s God’s people who have missed the boat. These are things they obviously should know. Not only could God’s “eternal power and divine nature” be clearly perceived, but He also revealed Himself by His holy prophets.
Everything that Isaiah says is rhetorical. It should be answered with a resounding “yes,” and yet it is not. The people know God. They are His creation. They bear His name. And yet, they don’t understand. Isaiah seems to be beating his head against a brick wall, for if these people are indeed God’s people, then they wouldn’t be doing the things that they have done up to this point in their history. They would have followed God’s Law perfectly. They would not have had other gods and idols. They would not have turned their backs to God and His Word. But looking at Israel’s history, that is exactly what they had done, time and time again.
If you want to know who God is, Isaiah gives the perfect description of Him. He is the Creator. He is the Sustainer. He is the Supreme Ruler over all. Nothing exists that God did not create. Israel has tried to put God in a box, define Him according to human standards, but God does not and cannot fit in a human-defined box. Luther, in his lectures on Isaiah 40 says, “Why do you want to make God? Read what was said to you above. God already is, He sits in the dome above the earth. This God already exists, and He is incomprehensible, sitting at the same time in heaven and on earth. And you, ungodly one, will not hear. You try to confine Him to a little statue and to reconcile His immeasurable mercy and grace with a little piece of workmanship.”
Israel didn’t fully understand who God was; if they had, they would not have strayed so far from Him and His Word. One would think that given enough time and poor choices, God’s people would learn. However, that was not the case. They would repent when things got beyond their control, pray to God to rescue them and God would rescue. Once things got better, Israel went back doing their own thing.
It has been said, “Those who cannot remember the past are condemned to repeat it.” That is indeed true, for we continue today to turn away from God, thinking that we can do whatever we want, whether it conforms to God’s Word or if it contradicts God’s Word.
Try as we might, regardless of what we think or say or do, God is the ultimate authority. His Word is the ultimate authority. God is what we are not, the Holy One. The fact that God is the Holy One separates Him from all His creatures. He is what we are not – perfect. Yet, that is what desires to share with us – perfection. When man was created, man was created in the image of God, to be holy and without sin. After the Fall, that is no longer the case. And so God sends forth His Son to restore what was destroyed by sin. Christ comes, not to destroy but to restore. We have already been destroyed through the work of sin. What is needed now is restoration, making whole again the relationship between God and man.
The reason God’s people of old exist and we continue to do so is only because of God’s great strength and mighty power. It is through that strength and mighty power that we see God sacrifice His only Son in order to make right what had been wronged through Satan’s temptation of man. All that was necessary for salvation would be accomplished through the giving of God’s Son. Through His life, death, and resurrection, all sin that separates us from God has been cleansed and purged. God no longer sees the utter depravity of man’s sin, but now sees the forgiveness won for us by Jesus Christ.
This was the promise made so long ago to God’s people and yet they had forgotten it, chose to ignore or whatever sinful man does that takes them away from God. When we are separated from God, when we want nothing to do with God, God does not share the same sentiment. God seeks us out, continuing to seek us out until we return to Him, for the will of God is that all men would be saved.
As Isaiah records his words, Israel had two burning questions that kept coming back to the forefront. The first question: Could God help them? The second question was a follow-up to the first: Would God help them? Yes, God could definitely help Israel. Would God help them? Absolutely, for they are His people, regardless of all the times they fell away from Him.
Those questions that Israel continued to ask are the same questions that we ask today. When we get in over our heads due to sin, we wonder if God could and would help us. We have God’s assurance that the answer is indeed yes, for we are God’s creation and He has promised to be our God through thick and thin. He promises to be our God when we fail to be His people. He promises to be our God even when we do not want Him.
That promise of God is assured in the words of Isaiah: “He does not faint or grow weary; his understanding is unsearchable. He gives power to the faint, and to him who has no might he increases strength…. But they who wait for the LORD shall renew their strength; they shall mount up with wings like eagles; they shall run and not be weary; they shall walk and not faint.” We have God’s promise that He will always be with us, to care and provide for us, not out of a sense of obligation, but from a loving nature of Father to child.
As Isaiah asked at the beginning of our text, “Do you not know? Do you not hear? Has it not been told you from the beginning? Have you not understood from the foundations of the earth?” We need not wonder or question, for we have been told. We have God’s Word of assurance for us. We know that we do not have a God that is aloof, one that is distant from His people. Rather, we have a God who is as personal to us as He can be, for He has sent His Son into our flesh, to live and die for us, so that all would be restored. In Jesus’ name, amen. Now the peace of God that passes all understanding keep your hearts and minds through faith in Christ Jesus, amen.
