Heraclitus wrote over 2,000 years ago that:
Nothing endures but change.
The variant of this I grew up hearing all the time was:
The only constant in life is change.
Then again... I also remember that I've heard the opposite said many times as well.
Things will never change [but they typically do].
Life is all about change. The only thing I've ever known in life not to change is God. While my understanding of God has changed as I've grown up, God has been a rock on which I could depend upon. God doesn't flip-flop on the issues. He doesn't rewrite history to spin the truth of actual events. God just "is". Despite how the winds may blow from one day to the next I can rest assured that no matter what each day will brings he'll be with me each step of the way. How about you?
