How does religion explain infant deaths?

Purgatory is really an unfounded belief of the Catholic church. The Bible does not talk about purgatory in this day and age. There is scripture that confirms that before Christ died on the cross, the souls that died before that, went to a holding place called Paradise. That's where Jesus went after he died, to minister to the souls in Paradise, which at that time was in one of the compartments in hell, but not the bad part of hell. There is scripture to back it up. But after that, that compartment is no longer used. It is empty, as now, people who died after Christ died on the cross and have accepted him as Savior, their soul immediately goes to heaven, but their body stays in the grave until Resurrection Day. Catholics also believe that we can pray one into heaven and there's not one thing in the Bible that confirms that. In fact, the Bible says just the opposite. To be absent from the body is to be present with the Lord. Once we die, there's no changing our destination. The Bible makes that clear and that's why a decision is needed to be made while we are still alive because there's no second chances after we die. The Bible says we either go to Hell or Heaven. There's no such thing as reincarnation.
