Thus says the LORD, …
Do not remember the former things,
or consider the things of old.
I am about to do a new thing;
now it springs forth, do you not perceive it?
I will make a way in the wilderness
and rivers in the desert. — Isaiah 43:16a, 18-19 (NRSV)

It is Christmas Eve. One of the reasons we still celebrate the new thing that God did in Jesus Christ so long ago is that we find reassurance for the new thing God is still about to do.
