Yeah, but they walked on their own two feet, so how can the Lord claim that He carried them on eagle's wings. Yeah, but it was Egypt and slavery they were leaving, so how can the Lord claim that He was brought them to Himself (Exodus 19).
This sums up what grace looks and feels like, and defines its purpose. If you haven't read my book, "Constant Forward Motion-the Running of the Lymphoma Ultra Series" maybe you should, for it describes running marathon's, 50 k's, Forty and Fifty Milers. Every step was my own steps, yet, I felt an unmistakable presence at times that could only be described as being carried "on eagle's wings". Some runs lasted 12 hours, and there was a tangible drawing to the finish line, that really felt like I was being "brought" to the Lord. During the R-Chop chemotherapy, certainly there were times of being completely out of it, filled with fatigue, nausea and mentally blurred. Yet, in the big picture, total view, looking back, I can also say, I felt "carried on eagles wings", being brought forward to the end of therapy to the Lord.
The indwelling presence of God carries a person through anything, with the end result of being brought closer to the Lord himself. In the Israelites situation, not even their shoes showed any wear, and I can't claim that as I only got about 350 miles out of each shoe.
Lord, thank you for carrying us on eagle's wings out of slavery into relationship with You.
