If you ask a travel agent how to get to Bethlehem you'll be booked on an El Al airlines flight to Tel Aviv, ride on an air conditioned coach up through the hills, probably pass through Jerusalem, and then into the tourist trap called Bethlehem. 

Ask anyone in the New Testament how you get to the little town of Bethlehem and they'll say, "Go out to the desert, keep going till you get to the River Jordan. You can't miss it. You'll find a man out there, standing knee deep in the water, baptizing people. That's John the Baptizer. You ask him. If you want to go to Bethlehem, you've got to start there. There is no other way to get there."

They all say the same thing, all four gospels: Matthew, Mark, Luke, and John. They all say that if you want to go to Bethlehem, you've got to start with John the Baptizer.
