There have now been quite a number of reports from different people who have died or had near death experiences and seen heaven. Some of them are children. Almost all these reports give the same testimony – that babies who never saw the light of day are in heaven now! Praise the Lord!
I think it is wise to take eye-witness accounts seriously, especially when there are a number of them from different sources.
In any case, whether this report is true or not, and I suspect it IS true, the Bible tells us that there is a heaven and there is a hell. Even if you want to doubt testimonies like this, do not be in unbelief concerning God's Word – because unlike people, GOD is faithful.
