His cross was the means through which He opened a new form of relationship with The Father. It was the “to-do” which was necessary. And only one man could do it! Jesus. Thanks. He taught, did symbolic things, prepared a people, but the cross was His Work alone-the cross was the most heroic action in history, and could have only been accomplished by Jesus. And He did it! It opened a new way for all of humanity to enter into direct communion with The Father again. The cross was the deed which changed all of history. His actions on the cross opened an entirely new way to God for all of humanity. Sin kept us from communion. The cross removed that stone, that block, through his dying as a sinless lamb. Think of sin as a wall between us and God. The cross tore down that wall. Jesus, alone, could have imploded that wall.
