Recently, one of the deaconess was sharing about this verse for devotion before our meeting. She asked an interesting question - why is it that God use the illustration of an eagle? Why not some other bird?
She did some research - and she found out a very basic truth - eagles very seldom flap their wings and fly, very unlike other birds. Instead, it would just spread out its long wings and just glide. Hardly any energy is used to flap its wings.
So what keeps it up in the air? It is the wind beneath its wings that lifts it up - very much like how a plane flies.
So when we wait upon the Lord and put our trust in him, we will soar like an eagle - but not by our own effort and strength - but by his power. He is the wind beneath our wings.
*This was the first version i've heard of this song. It was featured in the movie soundtrack of the movie Beaches and won the Grammy for the Record of the Year and Song of the Year in 1990.
