What the Bible says about Lot protected by Angels
(From Forerunner Commentary)
These angels reached out and pulled Lot in, so their hands were solid enough to yank Lot back into the house. Their hands did not just pass through Lot's arm, body, clothing, or whatever they grabbed him by. They had substance. Then they used some measure of spiritual power because, though the door was closed and those who were trying to get in were on the other side of it, they struck blind those who were outside so that they were disoriented and unsure about what was going on.
