Forget the former things; do not dwell on the past. See, I am doing a new thing!
Do you dwell on your past mistakes? Do you say, "Boy, I wish I would have know this years ago."? Does looking back prevent you from moving forward?
Well, here we read to forget it! Don't dwell on the past! You've grown, you've learned, and God's changed you! He's doing something new, so let Him have His way!
What new thing is He doing in your life?
