In Isaiah 40, the prophet declares that God does not faint or grow weary. Isaiah wants the people to know that their God has not grown tired. The people might be weary, but God is not. He hasn’t lost a step; He’s the Creator of the ends of the earth, but His work load does not exhaust Him. He operates out of the wellspring of His own eternal energy and passion. Unlike you and me, God does not grow weary.

In the 1990s, Energizer came up with a highly successful campaign: the Energizer Bunny. You’ve probably seen him: pink rabbit wearing sunglasses, banging on a drum. The commercial’s tagline says that Energizer batteries “keep going and going and going….”

Isaiah says the same thing about our God. He keeps going and going and going because of His eternal strength. Therefore, He is never too tired to deliver His people. Back to what we said last week, He’s never too tired to fight for His people. He doesn’t grow weary of shepherding our souls. God is inexhaustible — He operates out of His eternal strength.

And God is so strong that He has strength to share. As Isaiah says, He gives power to the faint and to him who has no might he increases strength. God generously shares His strength and power with those who are “faint.” This is an interesting word. It refers to those who have lost heart, those who don’t think they can go on any longer. And let’s face it: we all reach this point. At one time or another, we find ourselves worn out and weary, not sure we can go on any longer. I just want to ask the question again: I wonder how many of us feel that way right now.

But that’s where God meets us. He is promising here to give His own strength and power to us right there where we feel the weakest and the most weary. Isn’t that a comforting thought?

I saw a young girl in the airport once. One of the wheels on her suitcase had busted, so instead of rolling it behind her, she had to carry it through the airport. And she was crying, “Daddy, it’s too heavy!” And her Dad turned around and said, “It’s okay, let me carry it.” She handed the bag over to him and he lifted it up like it was nothing. And then he scooped her up in his arms and carried her, too!

This is our God. He gives strength to the weary.
