102. What does it mean when John says: “The Word became flesh and dwelt among us...”?

John 1: 14 states that the Son of God (the “Word”) became “flesh”, that is, a real human being. He was born in Bethlehem, grew up in Nazareth, and learned the profession of a carpenter there. He died in Jerusalem: He was crucified on Golgotha.
