Leon Morris (March 15, 1914 - July 24, 2006)

Here is a quote from one of Morris's books : Glory in the Cross (p.89)

"The atonement is not ... a way of excusing men from the tremendous moral demands that God makes on them ... [it is] only in the light of the atonement that those moral demands can be seen in all their fulness and met even approximately. Only as we appreciate that Christ had to die to put away our sin can we see sin for the enormity it is. Only then can we understand that certain things are sins, and therefore only then can we really grasp the magnitude of the moral demands that God makes on us."
