Why is it a good idea for us to heed God’s word and build memorials to His greatness and His faithfulness in our lives? Because, one day the river could be low. One day, things could get tough. Where’s our memorial? What will we be able to look to that helps us say, “OK, I remember what God did and I have come to trust Him?" Some day our river will be low, we’ll need some stones, a memorial, that helps us remember that God is good, that He is great, and that He is able. Something that reminds us that God has done it before and He is our hope.
One day it will be essential, because the day will likely come, when the memorial, our memory of God’s faithfulness, may be all we have to hang onto.
