1hole,
The world will have embraced a god. My expectation is that when Christ comes back that people all around the world will indeed be surprised. As previously stated, I've come to think that Christ's return happens after the two murdered witnesses stand up in the city, that it's going to be a big surprise as will be what 1st Thessalonians speaks to, that the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God.
PS,
Hope you had a fine Resurrection Day.
