“Who satisfieth thy mouth with good things; so that thy youth is renewed like the eagle’s.” – Psalm 103:5
This verse tells us that God satisfies us with good so that our youth is renewed. The two words ‘so that’ reveal that our satisfaction in God is the means that God uses to grant us His mighty strength. The ‘good’ that is the source of our satisfaction is His presence and His plan for us, which are detailed in the next few verses. Nothing else but God can satisfy us; it’s how God designed us.
The eagle is the strongest, most fearless, and most majestic of all birds. At about five years of age, the eagle will begin going through a molting process where it loses most of its feathers only to be replaced by new feathers. This gives the appearance of renewed youth in the eagle. During this molting process, the eagle will look sick and weak, but as the process completes, the eagle has the look and feel of renewed strength and energy.
This gives us the thought that the true believer on the Lord Jesus Christ retains enthusiasm and zealousness for the Lord as he considers all the wonderful benefits that come from knowing the Lord.
