In preparing them for his ordeal of suffering and death, Jesus told his disciples they would "all fall away" in fulfillment of the prophecy, "I will strike the shepherd, and the sheep will be scattered" (Mark 14:27). There is an element of common sense here which is often overlooked. In Greek, the words for "apostasy" and "resurrection" are antonyms. There is the sense that one must "fall away" before one can "stand up again." In other words, the familiar teaching in Christian eschatology that there must first be a "falling away" before the consummation of all things, that is, before the resurrection, is rooted in this very basic premise.
Things would be quite different following the resurrection, however. Jesus assured his disciples that "after I am raised up, I will go before you to Galilee" (Mark 14:28). Rising from the dead, Jesus would restore the faith of those who had fallen away. The meaning and purpose of the resurrection is intensified by the fact that it would be preceded by the apostasy. Had there been no apostasy, there would have been no need for the resurrection; but because there was an apostasy, the power of the resurrection to restore all things is all the more glorious.
In order to appreciate fully what Jesus accomplished in rising from the dead, it is first necessary to realize how far we human beings have fallen from our original state of righteousness. We are children of Adam and Eve and, therefore, heirs of the great apostasy by which we lost our standing in right relationship with God. Only the cross can atone for our sin. Only the resurrection can restore our standing with God.
