We are looking at Isaiah 40:28-31 this morning, verses which are both powerful and encouraging.
Have you not known? Have you not heard? The Lord is the everlasting God, the Creator of the ends of the earth. 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. 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.
We see in these verses that . . .
God’s people were weary
They were discouraged and overwhelmed because they had been defeated by another nation and taken from their homes and now were living as strangers and exiles in a foreign land – Babylon. Yet they also knew, they had heard, that God still had a purpose for them as a people. And that God had promised to bring them back to their home – Jerusalem.
But in their weariness and despair they wondered: Can God’s promise really be true? Is God really able to come through on it? They were enslaved by the most powerful empire of their day and they were at the mercy of its king. How in the world would they ever be able to leave and return home
Considering all this they were tempted give up, “to faint” as our text says. In the ordeal they were facing, as v. 30 says, “even youths shall faint and be weary and young men shall fall exhausted.” Even the strongest among them were overwhelmed.
And so the prophet speaks God’s word to them.
First of all, he tells them that God is able to come through for them. God is the everlasting God. God is the God who created all things. God is the God who doesn’t grow weary or faint. You know, God isn’t now all of a sudden tired and weak and thus unable to help Israel.
Yes, their situation seems impossible, but God is able to bring them back to the land at the appointed time. God is able to keep his promise to them.
Secondly, the prophet tells them that the Lord can strengthen them. Instead of giving up in their difficult situation, to “faint” or to “fall exhausted,” they should “wait for the Lord” – v. 31. To “wait for the Lord” means to have an expectant and confident trust in God and his promises, knowing that God has heard us and knows our situation and will come through.
The prophet is saying, if they look to the Lord in their difficult situation, that is, if they wait on the Lord, God will strengthen them – v. 29. Even though it’s so bad that it overwhelms the strongest among them in their own strength, God gives of his strength to those who look to him. And because of this, their strength will be renewed – v. 31. And they will be able to walk, and to run, and to fly. That is, to keep going even in the midst of their troubles in exile, knowing that God can handle their problems and will deliver them.
And you know what? God did come through for them! God raised up another nation which took over and released the Israelites to go to their home. The promise was fulfilled, they were returned to their land, and God worked out his purpose for them.
Well, I share this with you today because . . .
We too can become weary
We all go through difficulties, whether health crises, financial crises, broken relationships with family or friends, personal failures and weaknesses or in general – experiences of deep pain and suffering.
And we will continue to do so throughout our lives. Our faith is not “escapist.” A false promise that things will be just fine, if you have enough faith. No. This life is full of trials and God doesn’t just step in and take them all away.
And as we go through these hardships we can become overwhelmed, discouraged and faint. And even though we know that God has a purpose for each one of us, and that God has given us “his precious and very great promises” as 2 Peter 1:4 says; promises to help us, to save us and to bring us into his eternal kingdom – we too still doubt at times. We become fearful and exhausted.
And in our despair we ask: Can God’s promises really be true? Is God really able to come through on them? And will God come through for me? We are tempted to give up, “to faint,” to give in to our weariness.
And so we too need to hear the message of the prophet, because there is a word in this for us, each one of us. We need to hear and know that God is able to come through for us. For you and for me!
We may be overwhelmed by our circumstances, but God is not. v. 28 says, “Have you not known? Have you not heard? The Lord is the everlasting God, the Creator of the ends of the earth. He does not faint or grow weary; his understanding is unsearchable.” God is able to help us. God is able to keep his promises to us, just as he did with the Israelites.
And we also need to hear and know that the Lord can strengthen us. We too are to “wait for the Lord” – v. 31, knowing that he hears us and knows our situation. And we are to put our hope and trust in God and rely on him. And when we do this God gives us of his strength. As 29 says, “He gives power to the faint, and to him who has no might he increases strength.”
We tap into the strength of the Everlasting God himself; we lean on him, the One who never grows weary or faints. In this way, despite our troubles, our strength is renewed. As 31 says, “the Lord shall renew their strength.” And through this strength we are empowered to move forward in our times of difficulty, because we hope in the Lord; because we know that he will fulfill his promises to us.
We can move forward, as v. 31 says, “They shall mount up with wings like eagles; they shall run and not be weary; they shall walk and not faint.” In the midst of our problems we will walk and not faint, we will run and not be weary, we will mount up with wings like eagles.
Are you weary this morning? Do you feel overwhelmed? God invites you to come to him and find hope and strength.
