I have a question regarding John 3:13. It says that 'no one has ascended into heaven...' What does this verse mean? I have a sort of vague idea that it means that no one has gone into heaven and come back to explain celestial things, just Jesus. The question came up as I was reading the Bible and I noted this verse. I am in constant contact with Jehovah Witnesses and I know they might use this verse to support their belief that we don't go to heaven when we die. Thanks guys.
