The fact that Jesus was crucified in a place called Calvary/Golgotha teaches us that...
Jesus' death was an historical fact (contemporaries knew the place well)
Jesus was rejected by men (outside the city: Jn. 19; Heb. 13)
Jesus took away our sins forever (like the scapegoat in Lev. 16)Jesus was cast out of old Jerusalem so that we would be able to enter the new Jerusalem!
