“Have you not known? Have you not heard? The LORD is the everlastiong God, the Creator of the ends of the earth. He does not faint or grow weary; his understanding is unsearhable. He gives power to the faint, and to him who has no might he increases strength. Even youths shall faint and be weary, and young men shall fall exhausted; 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.” Isaiah 40:28-31
Have you ever been in that “deer in the headlights” moment when your spouse somewhat frustratedly says, “Don’t you know?! Didn’t you listen to me?!” And, we regrettably acknowledge our failure to remember or pay attention to what our beloved has said.
Well, that is kind of the tone and intent of the two questions that the prophet Isaiah poses to God’s people. They had forgotten or failed to pay attention to the vital truth of God that they desperately needed for sanctification, sanity, stability, and strength.
In this passage there are at least three great truths of God that we ought to know:
1. Don’t you know that the covenant keeping God (“LORD”/”Yahweh”) does not give out or give up? “He does not faint, or grow weary.” When someone faints they succumb to some circumstance outside of their control that causes them to give out. For whatever reason (fright, poor blood circulation, pain, etc.) their body can take no more, and it gives out. The everlasting God is not subject to the pressures and surprises of persons or circumstances. He will never be forced to faint. He will never give out in a moment of our need. Nor, will he “grow weary.” Which is to say that he will never give up out of frustration or discouragement due to an inability to accomplish what he wants. For he is the “Creator of the ends of the earth.” Nothing stands in the way of the Almighty! He does all that he pleases. This is good news for us as God’s children. He won’t give up on us, nor will he give out on us when we need him most.
2. Don’t you know that our God knows? “His understanding is unsearchable.” The Lord knows! He knows you and me. He knows us personally and intimately (Ps. 139:1-6). He knows our families, churches, communities, countries. He knows what we need; when we need it; and how to make it happen. He knows the end from the beginning (Is. 46:10). He possess all knowledge and all wisdom. Just look at the world with all of its intricate details, multiple varieties, purposeful systems, and immeasurable vastness! The Lord created and sustains it all by the word of his power (Gen. 1:1-3; Ps. 33:6,9; Heb. 1:3). Our God’s understanding is unsearchable! We do not face a problem that he can not solve. We do not have a need that he cannot meet. We do not have a lack that he cannot supply.
3. Don’t you know that the Lord is a willing Giver? “He gives power to the faint, and to him who has no might he increases strength.” Our God is a generous Giver! He willingly gives power, ability, and strength to his children who would otherwise give up and give out. Unlike God we do faint and grow weary. Thankfully, our Lord generously gives us the power to achieve and to persevere. The apostle Paul wrote, “He who calls you is faithful; he will surely do it,” and, “…the Lord is faithful. He will establish you and guard you against the evil one” (1 Thess. 5:24; 2 Thess. 3:3).
In our stubborn independence, even the strong weaken and grow weary, and yield to exhaustion and frustration. But, for those who know the Lord and therefore actively (prayer, faith, worship) wait for him, we will experience the benefits of our all-sufficient God; our strength will be renewed. We will soar in faith and faithfulness. We will run and walk without wearying and fainting.
