And then there's John 3:16--For whosoever believeth in me, shall not perish but have eternal life."
I believe children RETURN to heaven, because of Matthew 19:14--Jesus said, "Let the little children come to me, and do not hinder them, for the kingdom of heaven belongs to such as these."
As far as deathbed conversions, I believe if they are sincere in their beliefs, and are truly remorseful and seek forgiveness, they will go to heaven.
The thief was remorseful and went to heaven, so I have to believe that my mother, who found Christ in the last months of her life, and sought forgiveness for her sins, also went to heaven.
As for the faith without works, I think that applies to people who think their belief in Jesus is a free ticket to heaven, and they can do anything they want without guilt and be forgiven for it.
That's the gospel according to Lynn.
