What does it mean to sing a new song? What's wrong with the old songs?
God is at work in each day of our lives. God's gifts call us to fresh praise for
what God is doing right now as well as what God has done in the past.
We celebrate the festivals, the high points of Jewish and Christian faith
to remember what God did in the past and to believe that God will act the same way
in new situation in our present and future.
As we step out in faith in each situation we are indeed declaring God's
glory to the nations.
