It is on the mug, the fridge magnet, the card someone gave you the week everything went wrong. Eagles. Running. Walking. Not fainting.<\/p>\n\n\n\n<p>And if you are honest, there are days it lands a bit hollow. You are tired. You have been waiting on God for a long time. And you do not feel like an eagle. You feel like someone who has read a nice sentence one too many times.<\/p>\n\n\n\n<p>Here is the good news: Isaiah 40:31 explained properly is not a pep talk at all. It is the last line of an argument. And the argument starts with someone saying exactly what you might be feeling right now.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Isaiah 40:31 Explained: Read the Verse That Comes Four Lines Earlier<\/h2>\n\n\n\n<p>Almost nobody quotes Isaiah 40:27. But verse 31 is the answer to it.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p>&#8220;Why sayest thou, O Jacob, and speakest, O Israel, My way is hid from the LORD, and my judgment is passed over from my God?&#8221;<\/p><cite>Isaiah 40:27, KJV<\/cite><\/blockquote>\n\n\n\n<p>Put that in plain words. <strong>&#8220;God can&#8217;t see what I&#8217;m going through. My case has been skipped.&#8221;<\/strong><\/p>\n\n\n\n<p>That is the complaint. It is not a polite one. And the passage does not scold the person who says it. It answers them. Verses 28 to 31 are one long reply to a tired person who feels overlooked.<\/p>\n\n\n\n<p>That matters. Isaiah 40:31 was never written for people who already feel strong. It was written for people who have started to suspect nobody is watching.<\/p>\n\n\n<div class=\"convertkit-form wp-block-convertkit-form\" style=\"\"><script async data-uid=\"6491fb8269\" src=\"https:\/\/bgodinspired.kit.com\/6491fb8269\/index.js\" data-jetpack-boost=\"ignore\" data-no-defer=\"1\" data-no-optimize=\"1\" nowprocket><\/script><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Who Isaiah 40 Was Written For<\/h2>\n\n\n\n<p>Isaiah 40 is a turning point in the book. The chapters before it carry hard warnings. Then chapter 40 opens with a completely different tone:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p>&#8220;Comfort ye, comfort ye my people, saith your God. Speak ye comfortably to Jerusalem, and cry unto her, that her warfare is accomplished, that her iniquity is pardoned&#8230;&#8221;<\/p><cite>Isaiah 40:1-2, KJV<\/cite><\/blockquote>\n\n\n\n<p>The people in view here are people facing exile in Babylon. They are far from home, or about to be. Their city is broken. Their temple is gone or going. It would be very easy for them to conclude that God had simply lost track of them.<\/p>\n\n\n\n<p>So when verse 27 says &#8220;my way is hid from the LORD,&#8221; that is not a theory. It is a whole nation&#8217;s lived experience. And the chapter answers it in three steps.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step one: God does not run out<\/h3>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p>&#8220;Hast thou not known? hast thou not heard, that the everlasting God, the LORD, the Creator of the ends of the earth, fainteth not, neither is weary? there is no searching of his understanding.&#8221;<\/p><cite>Isaiah 40:28, KJV<\/cite><\/blockquote>\n\n\n\n<p>The answer to &#8220;God can&#8217;t see me&#8221; is not &#8220;try harder.&#8221; It is a statement about God. The one who made the ends of the earth does not get tired, and does not lose the thread. Your case has not been skipped, because the one reading it never needs a break.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step two: God gives strength to the ones who have none<\/h3>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p>&#8220;He giveth power to the faint; and to them that have no might he increaseth strength.&#8221;<\/p><cite>Isaiah 40:29, KJV<\/cite><\/blockquote>\n\n\n\n<p>Notice who qualifies. Not the fit. Not the faithful-feeling. The faint. The ones with &#8220;no might.&#8221; Being empty is not a disqualification here. It is the entry requirement.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step three: even the strongest humans run out<\/h3>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p>&#8220;Even the youths shall faint and be weary, and the young men shall utterly fall: But they that wait upon the LORD shall renew their strength; they shall mount up with wings as eagles; they shall run, and not be weary; and they shall walk, and not faint.&#8221;<\/p><cite>Isaiah 40:30-31, KJV<\/cite><\/blockquote>\n\n\n\n<p>Young, healthy people with the most energy in the room still hit the wall. The passage says so plainly. Human strength has a limit, and everyone reaches it. (We looked at how the promise then steps down from soaring to running to walking in <a href=\"https:\/\/bgodinspired.com\/index.php\/prayer\/prayer-for-strength-during-difficult-times\/\">this prayer for strength during difficult times<\/a>.)<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The Two Words That Repeat<\/h2>\n\n\n\n<p>Here is the detail that is easy to read straight past. Look at the two words used about God in verse 28: God &#8220;<strong>fainteth not<\/strong>, neither is <strong>weary<\/strong>.&#8221;<\/p>\n\n\n\n<p>Now look at verse 30. The young men &#8220;shall <strong>faint<\/strong> and be <strong>weary<\/strong>.&#8221; Same two words.<\/p>\n\n\n\n<p>Now verse 31. The ones who wait &#8220;shall run, and not be <strong>weary<\/strong>; and they shall walk, and not <strong>faint<\/strong>.&#8221; Same two words again.<\/p>\n\n\n\n<p>The Hebrew does the same thing: the same pair of verbs is used all three times. So the passage moves in a deliberate line:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>God:<\/strong> never faint, never weary.<\/li><li><strong>The strongest people:<\/strong> faint and weary.<\/li><li><strong>The people who wait on God:<\/strong> not weary, not faint.<\/li><\/ul>\n\n\n\n<p>The people who wait on God end up described with God&#8217;s own words. The thing that is true of God starts becoming true of them. That is the promise. Not &#8220;you will feel pumped up,&#8221; but &#8220;what never runs out in God will be shared with you.&#8221;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What &#8220;Renew&#8221; Really Means in Isaiah 40:31<\/h2>\n\n\n\n<p>In English, &#8220;renew their strength&#8221; sounds like topping up a battery. The Hebrew word points somewhere slightly different.<\/p>\n\n\n\n<p>The verb behind &#8220;renew&#8221; is <em>chalaph<\/em>. Its basic sense is to change, or to exchange one thing for another. You can see it in Genesis 35:2, where Jacob tells his household to &#8220;be clean, and change your garments.&#8221; That word &#8220;change&#8221; is the same verb, in the same form, that Isaiah 40:31 uses for &#8220;renew.&#8221;<\/p>\n\n\n\n<p>So the picture is less like recharging and more like changing clothes. You take off the worn-out strength you arrived with, and you put on strength that is not yours. An exchange.<\/p>\n\n\n\n<p>And the word for &#8220;wait&#8221; fits that picture. It is <em>qavah<\/em>, which carries the idea of waiting with expectation rather than sitting idle. We unpacked that word in depth in <a href=\"https:\/\/bgodinspired.com\/index.php\/what-jesus-teaches\/wait-on-the-lord-hebrew-meaning-qavah-isaiah-40-31\/\">The Hebrew Word for &#8216;Wait&#8217; Isn&#8217;t Passive<\/a>. Put the two together, and &#8220;wait upon the LORD&#8221; is not a waiting room. It is staying close enough to make the trade.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why Eagles?<\/h2>\n\n\n\n<p>Eagles are not a random choice. They already meant something to the people hearing this. When God first brought Israel out of Egypt, the picture used was this one:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p>&#8220;Ye have seen what I did unto the Egyptians, and how I bare you on eagles&#8217; wings, and brought you unto myself.&#8221;<\/p><cite>Exodus 19:4, KJV<\/cite><\/blockquote>\n\n\n\n<p>For exiles far from home, &#8220;wings as eagles&#8221; would have echoed the first rescue. The God who carried them out of one captivity had not forgotten how to carry them home from another. Psalm 103:5 uses the same image for renewal: &#8220;thy youth is renewed like the eagle&#8217;s.&#8221;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What This Changes for You on a Tired Day<\/h2>\n\n\n\n<p>If you read Isaiah 40:31 as a pep talk, it quietly puts the weight back on you. Be the eagle. Find the energy. Stop being tired.<\/p>\n\n\n\n<p>Read in context, it does the opposite. It starts by letting you say the hard thing out loud: &#8220;I feel unseen.&#8221; It agrees that your strength runs out, because everyone&#8217;s does. And then it offers a trade, not a test. Your faint-and-weary for God&#8217;s never-faint, never-weary.<\/p>\n\n\n\n<p>You do not have to feel strong to qualify. You just have to stay close enough to make the exchange. Some days that looks like soaring. Most days it looks like getting through the next hour without collapsing. Both count.<\/p>\n\n\n\n<p>Jesus made the same offer in different words: &#8220;Come unto me, all ye that labour and are heavy laden.&#8221; We looked at the word He chose for that kind of tiredness in <a href=\"https:\/\/bgodinspired.com\/index.php\/what-jesus-teaches\/matthew-11-28-meaning-greek-word-kopiao-physical-exhaustion\/\">this study of Matthew 11:28<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Actions to Take<\/h2>\n\n\n\n<ol class=\"wp-block-list\"><li><strong>Say your verse 27 out loud.<\/strong> Finish this sentence honestly, in one line: &#8220;The part of my life I feel God can&#8217;t see right now is&#8230;&#8221; Isaiah 40 starts with that complaint, so you can too.<\/li><li><strong>Name one thing you are carrying that you could trade.<\/strong> Write it on a scrap of paper or in your phone notes.

Help me stay close enough to make that exchange, one ordinary step at a time. Amen.<\/em><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Discussion Question<\/h2>\n\n\n\n<p>Why do you think Isaiah 40:31 is so often quoted without the complaint in verse 27 that it answers?

Only one group gets to borrow God&#8217;s version.<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Questions and Answers About Isaiah 40:31<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">What is the meaning of Isaiah 40:31?<\/h3>\n\n\n\n<p>Isaiah 40:31 promises that people who wait on God will have their strength renewed: they will mount up with wings as eagles, run without growing weary, and walk without fainting. In context, the verse answers a complaint in Isaiah 40:27 from people who felt God could not see their situation, and it reassures them that God never grows tired and gives strength to those who have none.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What does &#8220;renew their strength&#8221; mean in Hebrew?<\/h3>\n\n\n\n<p>The Hebrew verb translated &#8220;renew&#8221; in Isaiah 40:31 is chalaph, which basically means to change or exchange. The same verb appears in Genesis 35:2, where Jacob tells his household to &#8220;change your garments.&#8221; That suggests the renewal in Isaiah 40:31 is an exchange of worn-out human strength for strength that comes from God, rather than a simple recharge.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Who was Isaiah 40:31 written to?<\/h3>\n\n\n\n<p>Isaiah 40 begins a section of the book of Isaiah addressed to God&#8217;s people facing exile in Babylon. The chapter opens with &#8220;Comfort ye, comfort ye my people&#8221; and speaks to a nation far from home who had begun to believe God had forgotten them, which is why Isaiah 40:27 quotes them saying, &#8220;My way is hid from the LORD.&#8221;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Why does Isaiah 40:31 mention eagles?<\/h3>\n\n\n\n<p>Eagles already carried meaning for Israel. In Exodus 19:4, God describes bringing Israel out of Egypt by saying, &#8220;I bare you on eagles&#8217; wings.&#8221; For exiles hearing Isaiah 40:31, the eagle image echoed that first rescue and suggested God could carry them home again. Psalm 103:5 also links eagles with renewal: &#8220;thy youth is renewed like the eagle&#8217;s.&#8221;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What is the verse before Isaiah 40:31?<\/h3>\n\n\n\n<p>Isaiah 40:30 in the King James Version reads: &#8220;Even the youths shall faint and be weary, and the young men shall utterly fall.&#8221; It admits that even the strongest people run out of strength, which sets up the promise in Isaiah 40:31 that those who wait on God will run and not be weary, and walk and not faint.<\/p>\n        <div class=\"booster-block
