On Mark Lowry's blog yesterday, the teacher talked about how Isaiah 40:31 starts out with eagles soaring, then running, then walking. Kind of how when we start out the day with a Bible Study, and then how we leak all day...how we need constant renewal.
Isaiah 40:30, 31: Even youths grow tired and weary, and young men stumble and fall; but those who hope in the Lord will renew their strength, they will oar on wings like eagles. They will run and not grow weary. They will walk and not faint.
NAS version puts verse 31 this way:
Yet those who wait for the LORD
Will gain new strength;
They will mount up with wings like eagles,
They will run and not get tired,
They will walk and not become weary.
