Here I am, living in the DFW area and just surviving my 5th snow day from work, and 3rd from school in the matter of a week and a half (We didn't do this good as children growing up in NYC), dealing with temperatures in the teens, thinking about warmer weather (like the 60's to 70's we are supposed to have in a couple of days).
Thinking about how quickly we will forget the ice and the cold when we are in the throes of some 100+ degree summer days. Makes me think of how long God remembers in comparison to how long we do not. Of what He chooses to forget as opposed to what we cannot seem to remember:
God is not unjust; he will not forget your work and the love you have shown him as you have helped his people and continue to help them.
When I fed them, they were satisfied; when they were satisfied, they became proud; then they forgot me.
For I will forgive their wickedness and will remember their sins no more.
and did not remember the LORD their God, who had rescued them from the hands of all their enemies on every side.
He will wipe every tear from their eyes. There will be no more death or mourning or crying or pain, for the old order of things has passed away.
This is just a small sampling of what you can find between the covers of your Bible.
He chooses to remember His promises, we choose to forget what He has done for us. And in order for us to live in eternal harmony with Him, we are not going to remember all the junk of our earthly past.
We remember to forget; He chooses to forget to remember.
