“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.” (Isaiah 40:31)
The phrase “renew their strength” in Isaiah 40:31 means that God will exchange (swap, or trade) their strength. Just like you might change the old tires on a car, or change into clean clothes after playing in the mud, God will change the strength of those that trust in Him through His Word. What kind of strength does God give? God’s Word says it is the kind that causes us to “mount up with wings as eagles.”
Did you know that eagles molt (lose or shed) their feathers as the old feathers get worn out? New feathers replace the old ones, increasing the eagle’s ability to do what it was created to do! When those new feathers grow in, the eagle has more power for flight, because its feathers are new. If the eagle did not molt its worn-out feathers and get new feathers, eventually it would not be able to fly at all.
We need God’s strength for everything! We cannot obey, we cannot love, and we cannot do truly good works without God’s strength. But the strength we had yesterday might already be used up on yesterday’s activities. So what should we do? We must go again to God and His Word today and believe what He says. We will gain (get) new strength as we believe God through His Word.
What is simply outstanding is that when the new strength you get for today has run out, there will be more to replace it. Why? Because the strength’s source is God. God never runs out, gets tired, or grows old. God is the Source of all strength, and He enjoys giving His children what they need as they trust in Him.
God always has more strength to give because He is all-powerful.
