Verse to ponder?

These verses really struck me at church today, they are Isaiah 43 v 18-19 (NIV):

Forget the former things;
do not dwell on the past.
See, I am doing a new thing!
Now it springs up; do you not perceive it?

Here it is in New Living Translation:

But forget all that—
it is nothing compared to what I am going to do.
For I am about to do something new.
See, I have already begun! Do you not see it?
