Here is a simpler last verse, especially for children's pageants, but for other uses as well:

So that is what we saw and heard:
full skies of angels above the earth
and a child and manger that made it clear
Messiah meant for us, at last, is here!

(Depending on how the song fits into your pageant, you could also eliminate the initial shout of "Tell the story!")
