So Christ lay entombed; but He was not there. He was in the world of spirits. The place of disembodied spirits was called, by the Jews, Sheol. It had two divisions, Paradise and Gehenna. Christ, we know from His own words, went to the former; and from Peter we gather that He also went through the realms of Gehenna, proclaiming His victory.
The practical conclusion of the whole is, however, contained in Romans vi. Just as the body of Christ after crucifixion was buried in the grave, so our sinful, sensual, selfish selves must be done away in the grave of forgetfulness and oblivion and disuse--buried with Christ, "that like as Christ was raised from the dead, through the glory of the Father, so we also should walk in newness of life."
