Is it possible to just visit heaven? My church had a guest speaker that said he died and was at the gates of heaven for 90 minutes. Can someone tell me where to read in the bible about seeing if this is possible? I just have trouble believing this.
YES, it is possible to visit Heaven. Some people have visited Heaven before they died.


  I know a man in Christ who fourteen years ago was caught up to the
  third heaven. Whether it was in the body or out of the body I do not
  know--God knows. (2 Corinthians 12:2, NIV)
