But those who wait upon the LORD will renew their strength; they will mount up with wings like eagles; they will run and not grow weary, they will walk and not faint. – Isaiah 40:31
Don’t get tired!
When God gives us strength, it is not so we can barely finish. We might think this if the passage only talked about walking and not being faint, as if we labor through some task and have just enough to keep going. But…
We run, and we don’t get weary even then!
With God’s power we don’t just plod along. Runners can stumble, collapse, and even be unable to continue. But to run and never become weary? This means endless stamina. We are not “barely finishing” but able to run as fast at the end as in the beginning. God gives us a new kind of strength, one that we know is not from ourselves. We know we get faint, and we know we can’t keep running and not get tired. But God’s power renews us, and we can!
This new strength comes from our hope in the Lord. It comes through faith.
All of that would seem enough and even extraordinary, but God keeps going. We not only tirelessly run, we will soar as if we had eagle’s wings! We will be so energized that it is as if we are sailing though the air. What we might have seen as needing help to just get through, God turns into an incredible flight of His never-ending grace, love and power.
