Peace on Earth?

It was said at the birth of the Messiah, that there was to be peace on earth and goodwill toward men.

That seemed to paint a big picture.

But it was also said that despite Messiah's coming, their feet needed to be GUIDED into the way of peace.

That sounded narrower.

The bigger picture will indeed come, in the new heavens and earth - but the only scheme of entering it was inaugurated for Israel first through the Gospel, then Gentiles also were included in the same Gospel-scheme.
