In Chapter 40 we see God beginning to reveal his plan for everyone and the hope that we have in Him. Now God continues to speak in chapter 41. He is speaking to people in distant lands, the idol worshippers. He tells them to step into His holy courtroom and present their evidence. Then God begins to explain that He alone is in control of everything. The things that happen in an individuals life, along with worldwide events on a colossal scale are all in His power. People who believe and trust in Him, as well as people who don't, are all subject to God's ultimate plan.
So when we see things on the news about events happening around the world, don't think that they are out of God's control. He is still on the throne and is in control of all things. Remember that it is all a part of His loving plan. (even though to us, it doesn't seem loving)
In verse 8 God addresses Israel through Isaiah and tells them not to worry. He's got this. He will protect them and He will be their ever present help in times of need. (psalm46) God continually reminds them not to be afraid. Then He tells the Israelites that he will not only protect them and help them, but He will also provide for them. God is reassuring them that He is always there for them. Fear is a crippling emotion. Have you ever been so afraid that you could't move or think straight? I certainly have! God wants us to live our best lives for Him. He wants our best. How can we give Him our best if we are paralyzed by fear or can't even think straight? We cant. That is why God reminds us over 350 times in the Bible "Do not fear".
Then God readdresses the idol worshippers from the beginning of the chapter after they have laid out their case for worshipping idols. God asks them a simple question. "Can your idols tell you what will happen in the future?" He answers for them. "Of course not! Your idols don't even exist. They have no power." Then God proceeds to tell them some events that will happen in their future.
Chapter 41 of Isaiah is considered the great I WILL chapter. 14 times God reinforces His promises by saying "I will". Here are some of them: I will strengthen you. (Isaiah 41:1) I will help you. (Isaiah 41:10, 13, and 14) I will uphold you with My righteous right hand. (Isaiah 41:10) I will make you into a new threshing sledge with sharp teeth. (Isaiah 41:15) I will open rivers in desolate heights. (Isaiah 41:18) I will make the wilderness a pool of water. (Isaiah 41:18) I will plant in the wilderness the cedar and the acacia tree. (Isaiah 41:19) I will set in the desert the cypress tree. (Isaiah 41:19) I will give to Jerusalem one who brings good tidings. (Isaiah 41:27)
Did you know that God's promises are also for us today? 2Peter 1:4-5 says just that! And Galatians 3:29 states that if we are followers of Jesus, we are children of Abraham and heirs to God's promises.
In Chapter 42, He starts off with Behold! My Servant .... which is definitely Jesus. How do we know that? Because when God refers to other servants of His, like Moses, He uses a small letter s at the beginning of the word servant. But here we see a capital S. Isaiah follows up with a beautiful "song" straight from the lips of God about how Jesus will be a light to the world. He will bring justice. He will open the eyes of the blind man and set the captives free. The book of Isaiah is filled with references and prophesies about Jesus. Jesus is the hope of Israel and the whole world. The rest of Chapter 42 is about God's provision for Israel and their rebellion.
Chapter 43. God will allow Israel to be captured by Babylon, But He reassures them that they are still his people. He reminds them how He rescued them from Egypt, and He will do it again from Babylon. Has God ever been there when you needed Him most. He has for me. God wants us to remember those times, because if He did it before... He will certainly do it again. Chapter 43 ends just like 42.... the Israelites neglect to obey God.
Chapter 44 reminds the people of Israel that He alone is the one true God. Idols are mere artifacts made by human hands. They have no power... But he, God, Has ultimate power over everything.
Chapter 45 speaks of how God will use a non-Jew, Cyrus, to bring about His plan. They Israelite didn't think that God could, or would use anyone outside of Israel to bring about His plans.... But God can use whomever He pleases.
Chapters 46 and 47 are about Babylon. How they worship false gods. Those false gods are powerless when the one true God moves in to defeat them.
Chapter 48: God reminds Israel that He made promises to Abraham that ALL came true. So all these things that He is revealing now about being captured by Babylon, the hard hearts of God's own people and the ultimate defeat and fall of Babylon will certainly come to pass.
So to wrap it all up. God wants the Israelites to know that He is in control of all things present and all things in the future. God wants us to know the same thing. Sure, we'd like to know exactly what will happen, but that is where trusting God comes in. After all aren't our hearts and trust really the only things that we can give a God who owns everything? So during some of these dark days, hold tightly to God and trust Him for the days to come.
