God clearly calls His people to build spiritual memorials. A definition of a spiritual memorial, what the Israelites set up in Joshua 4 after being led across the Jordan on dry ground, would be "a monument to a spiritual high water mark in life."
What has God done in your life, in my life? And what have we done to commemorate it? Have we established things that will cause us to remember the wonderful things God has done? When was our latest trial? When was our latest victory? When have we seen God move? How are we commemorating that?
Why build memorials? Why remember? So we can say, "Those were the good old days"? Maybe, as long as the good-old days point us to a very good God, because that’s what He wants of us.
It was God’s idea to build memorials because He knows the hearts of people; He knows us very well. He knows how self-centered we are, how forgetful we are. How many times we gone before God, saying, "Lord, I need help -- again." How soon we forget. GOD WANTS US TO REMEMBER.
1 When the whole nation had finished crossing the Jordan, the LORD said to Joshua, 2 "Choose twelve men from among the people, one from each tribe, 3 and tell them to take up twelve stones from the middle of the Jordan from right where the priests stood and to carry them over with you and put them down at the place where you stay tonight." - Joshua 4:1-3
