If you believe in the trinity ( Father, Son, Holy Ghost ) consider this. It is easy to see that the Son is Jesus. And the Father should be the father of Jesus. But the Bible says in the first chapter of Matthew verse 18 that Mary was with child of the Holy Ghost. Verse 20 repeats that her child was conceived by the Holy Ghost. So isn't the Holy Ghost really the father of Jesus and the Father is not really the father? How can this be explained?
