Question: Do you think God uses means other than men for specific revelation (i.e. angels or stars)?
Answer: Yes! Paul’s conversion (see Acts 9) while traveling to Damascus to persecute Christians is a prime example of God using means other than preaching. In Paul’s case, Jesus did the preaching! I have had two conversations this week with people who shared stories about people who say that they had dreams or visions of Jesus who made them aware of their sin and their need for Him as their Savior.
I don’t think God uses stars because that would be general revelation.
