In Pilgrim’s Progress, when "the way" became rough, Christian and Hopeful found a path "very easy for their feet" (By-path meadow). How many times when the Christian way becomes difficult are we tempted to look for an easier way?
This chapter was Moses’ Farewell Address to Israel, and this verse was to the tribe of Asher. These people lived on a rocky seacoast, and shoes made only of leather would not have protected their feet from the sharp rocks. Thus, the importance of "shoes" made of "iron and brass."
There is an old saying, "We do not go to Heaven in silver slippers." Why? Because "the way" will, at times, be difficult. God knows this, and He gives us "equipment proportioned to our work, shoes fit for the road" (MacLaren). The durability of our shoes will match the roughness of the road.
So it is with our strength. God knows the road you will be traveling today, and He has promised to give you strength for today. This strength is not for weeks or months but for "days." God knows exactly the amount needed for today. When tempted to look too far ahead and begin worrying about the future, this verse is a good reminder that when we get to that part of "the way," God will provide the "shoes" (strength) that we need.
Write something about yourself. No need to be fancy, just an overview.
