IF you are a believer, Jesus' sacrifice was utterly necessary and is crucial in Christian theology. THE point was and is redemption from the sin of Adam and Eve ('the fall') and the conquest of death.--Christianity DOES teach physical resurrection.
Redemption through the of the death of the god followed by his resurrection is not an unusual religious belief. It is found in many fertility religions,many of which practiced human sacrifice.
