It was a trying experience for Joseph and Mary to undertake the rearing of this unprecedented combination of divinity and humanity, and they deserve great credit for so faithfully and successfully discharging their parental responsibilities. Increasingly Jesus’ parents realized that there was something superhuman resident within this eldest son, but they never even faintly dreamed that this son of promise was indeed and in truth the actual creator of this local universe of things and beings. Joseph and Mary lived and died without ever learning that their son Jesus really was the Universe Creator incarnate in mortal flesh. ~ The Urantia Book, 124:4.4
