Jesus put the question to them and the right
answer to settle the problem of His divinity
forever.

Jesus asked them whose son was the Christ?
Their answer was "David's".

Since they didn't believe that He was the true
Messiah, this meant they believed that when
the Messiah did come that He would be the
son of David. While Christ was the son of
David through His mother Mary, He wasn't
the son of David in His person.

He came to the world as the only begotten
Son of the Father/God!
