None. Who said the babies are in heaven?
Certainly not the Bible.
A-ha, now we are getting somewhere.
I have been told by more than one Christian that there are only 2 possible places to spend eternity after death, heaven or hell. No more, no less, just 2 - one or the other.
Is that not the orthodox Christian teaching?
Babies definitely die. So if there are no babies in heaven, does that mean that all babies go to hell?
Or is there a 3rd option?
If so, what is that 3rd option? Where can I find a discussion of "door no. 3" in the Bible? And is it open only to babies, or also to other persons who had no opportunity to demonstrate faith, due to ignorance?
Seriously, I'm not trying to be "smart", I want to understand - what you've described is (apparently) different than what I've been told.
