You're dancing on me here! Do you believe that that sign of the Son of man appeared in 70 AD or not??? Yes or No --
I thought you guys had all the answers -- so answer it.
Not at all. Without referencing Scofields Notes, you show us from the Bible where "the sign of the son of man" must "literally" mean the second coming.

Give it a shot Chipper and see what you can do. Exegetes some Scripture for a change.
