I dare say you will think it a very easy thing to stand still, but it is one of the postures which a Christian soldier learns not without years of teaching. I find that marching and quick marching are much easier to God’s warriors than standing still. It is, perhaps, the first thing we learn in the drill of human armies, but it is one of the most difficult to learn under the Captain of our salvation. The apostle seems to hint at this difficulty when he says, “Stand fast, and having done all, still stand.” To stand at ease in the midst of tribulation, shows a veteran spirit, long experience, and much grace.
