"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."
I love this idea... that as servants of God, we are renewed. Wings? That sounds pretty cool too. Might be symbolic rather than literal, but even so, the idea is a cool one. I've always loved the idea of running and walking without being tired at all.
Although the idea is cool, it is sometimes hard to see in our lives. We get tired, frustrated, and overwhelmed sometimes. Running makes us tired. Walking does too, especially up a long staircase. :) So, how does this verse apply to our lives? I think in a couple of ways. One, it applies right now in that the spirit can renew our energy and determination and keep us going when we need it. It probably requires some faith and a good reason, but it does work. I saw this on my mission many times. My body was exhausted, but the spirit kept me going, and engaged in the work, even when I was past my capacity and would normally be grumpy and irritable. Doesn't mean that we don't need to take care of our bodies, or get adequate rest, but if we are in need of the Lord's help in doing his will, he'll help us. Probably even to fly if necessary... the scriptures do talk about people being carried in the spirit to the tops of mountains. Not exactly wings, but it does sound pretty cool. :) Two, it applies later when we're resurrected as well. Then we will have bodies that are perfect and that aren't subject to earthly limitations. :)
Today, let's serve the Lord and do his will (waiting upon, like a server/waiter, right?), so that we can show our love for him and build Zion... and get the cool blessings of renewal as a nice side benefit. :)
