God bless you, it is prophesied in Isaiah 7:14 and Isaiah 9:6. About the messiah. God with us! Also John 1:1 and 1:14 shows that God has come in the flesh. That is the whole purpose of Jesus Christ. He is the perfect man, because He was God incarnated in the flesh. Which is the mystery revealed to us in these last days.

To further clarify please read 1 Timothy 3:16

God bless you in all of your studies!
