The Redeemer was to make two distinct advents to this world.
At the first, He lived our example, preached His own gospel, wrought miracles to confirm His divine mission, died our sacrifice, rose from the dead for our justification, and ascended to the Father’s right hand to plead the cause of the repenting sinner.
But He will appear in this world the second time to execute other parts of the grand scheme. The plan of redemption in its second stage provides for the resurrection of the just from the dominion of death and the grave to life immortal and eternal.
*The moral fitness for the next life must be obtained in this.
*The change to immortality is not a moral change. It is simply an
exchange of the corruptible body for one that will be incorruptible.
This second stage in the stupendous work of man’s redemption is expressed by the apostle thus: Philippians 3:21 Who shall change our vile body, that it may be fashioned like unto His glorious body.
And the Redeemer will not complete His work of redemption in a manner to leave man invisible and immaterial. When redeemed, the just will stand in all the tangible perfection of Adam’s unfallen manhood, with the exceeding glory of bodies fashioned like unto Christ’s glorious resurrected body."
