Note
As I age I need to keep writing myself a note to remind me of what I have to do. In fact I have to write myself lots of notes. Old age and a good short term memory do not seem to hand in hand.
I guess God understood that our memories are always going to be a problem. That is why we are told so many times in the Bible to talk and write about all the good things that God does for us. This is to keep us focused on the blessings that He showers us with on daily basis. It is also important for us to use our memories to teach our children about the faithfulness of God.
“And thou shalt teach them diligently unto thy children, and shalt talk of them when thou sittest in thine house, and when thou walkest by the way, and when thou liest down, and when thou risest up.” Deuteronomy 6:7
