THE birth of Jesus was prophesied long before it happened.  See Tab Page:  47 Old Testament Prophecies of coming Messiah.  He is the Son of God and was sent from Heaven to be born part human so he could experience and relate to our pains, challenges, and joys.  And, most importantly to pay the debt for our sins as our Savior. God, in His wisdom knows we can never be good enough for Heaven ourselves. 

   YET, Jesus was also God incarnate. See Tab Pages: Jesus in every book of the Bible and Prophecies in The Holy Bible, plus Fulfilled Prophecies of Jesus,   Witnesses that Walked with Jesus,  and New evidence on The Shroud Turin, and more. 

   ALSO, God has stated that He has the Old Covenant promise with the Land of Israel, through Abraham in the Old Testament times, that can't be broken.  As Christians, we are under the New Covenant. See Tab Page: The Ten Commandments.   

   THE History of Christianity needs to be studied to really understand what was happening in those times as many critics take things out of context. What really happened in The Crusades. Most of the people were not true Christians even though they claimed to be. Evil is in this world and will reign until Jesus comes back and the full plan of God is finalized.
