So, Satan is dumber than a equivalent mass of falling masonry - seems he hasn't read the end of the book.<quoted text>
Dunno how many they are - or have been - or will be. But I do know that the Bible says that there will be more of us going to hell than to Heaven. It says that the path to hell is wide - but the gate to Heaven is narrow and to choose the narrow gate.
Not all "Christians" will be going to Heaven - the Bible tells us that even satan believes in Jesus - and trembles at His Word. So it's not enough for people to "just" believe in God - they have to, as they Bible says, pick up the cross and follow Him.
And that's the Great Adversary?
Doesn't say much about the wit of your deity, does it?
Sherlock Holmes had Moriarty - you've got Howdy Doody.
Oh, how many Christians in the world today?
