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. –Isaiah 4:31 (KJV)
What does it mean to "wait upon the Lord?" Sometimes when I read that phrase, I think of servants waiting tables in a king's house. I picture myself in a black and white uniform, standing back and watching attentively, waiting for the king to indicate some way that I can serve those at the table. To me, that makes the waiting purposeful, even fun. In that picture, I get to play a small part in the king's important business. I get to be in a fancy place and use beautiful, ornate, precious things. It's rather thrilling—a little like flying with eagles—to think of that kind of "waiting upon the Lord."
