We have spent considerable time on resolving all of the issues which pertain to the parable of Abraham and Lazarus. They aren't in heaven, they're in sheol. This isn't metaphorical, it's accurate geology.
Abraham and Lazarus
The Witch of Endor
You may be skeptical of the idea that there's an underworld realm of the dead deep in the interior of the Earth, or that the souls of the Old Testament saints had to wait there for the messiah. That's understandable.
The Days Before Noah
The longsuffering of God waited in the days before Noah. Noah's flood saw the waters of the deep (tehom), being boiled out from under the Earth creating the open space that Jesus referred to as the great gulf (sheol).
Rebellious Angels
The angels who didn't keep their former domain are the rebellious angels who were cast out of heaven with Satan. We've made the case that the everlasting chains which they were bound by are Mosaic gravity.
July 13th
Jesus descended into the lower parts of the Earth. We can resolve this as being a place in the lower mantle, we euphemistically call it Abraham's bosom, the same location that he described in Luke 16.
