I find this sad that Christians are debating the birth of Jesus who came and died on the cross for our sins, as if they question him being born or not. His ministry was for 3-1/2yrs the Bible and history books tell us of him being born. It is the foundation of our salvation. Without his death, we are dead in our sins!!
John 1:1 In the beginning was the Word, and the Word was with God, and the Word was God.
2 The same was in the beginning with God.
3 All things were made by him; and without him was not any thing made that was made.
4 In him was life; and the life was the light of men.
KJV
John 1:12 But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name:
13 Which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God.
14 And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth.
KJV
