Maybe- maybe not! I know for sure Paul did see heaven and it continue to RADICALLY alter his life to serve Christ! Of teh movies and books I have read from these who sdaid they went to heaven- I do not se the kind of devotion that even approaches Paul or even Isaiah who saw the Lord lifted up and His train filling the temple!
But Jesus said
JOhn 3: 3 Jesus answered and said unto him, Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God.
man here is anthropos- which means human being! So unless "innocent babies" are not human, they need to be born again if they want to experience the kingdom of God!
Psalm 51:5
Behold, I was shapen in
iniquity; and in sin did my mother conceive me.
Psalm 58:3
The wicked are estranged from the
womb: they go astray as soon as they be born, speaking lies.
Ephesians 2:
11 Wherefore remember, that ye being in time past Gentiles in the flesh, who are called Uncircumcision by that which is called the Circumcision in the flesh made by hands;
12 That at that time ye were without Christ, being aliens from the commonwealth of Israel, and strangers from the covenants of promise, having no hope, and without God in the world:
I do not see any "time of innocence" where people are saved because they don't know better. If you see it in the bible show it!
If god chooses to save aborted babies in a polytheist culture like India that is His business. But He did not say it in Scripture. Just the opposite in fact.
