2 Corinthians 3 & 4

The very concept of resurrection is a person rising from the dead and being alive once again. Most christians support the idea that death is the seperation of the body and the spirit suggesting our spirit or spirit body moves on and continues to live after death. With no resurrection then, the spirit would live indefinitely as a spirit. If you believe in the resurrection of the Savior, then you would also have to believe that his spirit was reunited with his body which would have to mean his body and spirit would remain in this condition eternally. If not eternally, then this would suggest he would die again which is contrary to the whole concept of resurrection. Amulek taught of the resurrection -

"The spirit and the body shall be reunited again in its perfect form; both limb and joint shall be restored to its proper frame, even as we now are at this time...and even there shall not so much as a hair of their heads be lost; but every thing shall be restored to its perfect frame, as it is now, or in the body..." (Book of Mormon Alma 11:43 - 44)

Paul described the difference between our natural bodies and our resurrected bodies as -

"It is sown a natural body; it is raised a spiritual body. There is a natural body, and there is a spiritual body." (New Testament 1 Corinthians 15:44)

A spiritual body then does not mean a spirit body, but a resurrected body that is sustained or quickened by spiritual things. Then Elder Howard W. Hunter explained -

“There is a separation of the spirit and the body at the time of death. The resurrection will again unite the spirit with the body, and the body becomes a spiritual body, one of flesh and bones but quickened by the spirit instead of blood. Thus, our bodies after the resurrection, quickened by the spirit, shall become immortal and never die. This is the meaning of the statements of Paul that ‘there is a natural body, and there is a spiritual body’ and ‘that flesh and blood cannot inherit the kingdom of God.’ The natural body is flesh and blood, but quickened by the spirit instead of blood, it can and will enter the kingdom.” (Howard W. Hunter in CR, Apr. 1969, p. 138.)

Paul also taught -

"But now is Christ risen from the dead, and become the firstfruits of them that slept.
21 For since by man came death, by man came also the resurrection of the dead.
22 For as in Adam all die, even so in Christ shall all be made alive." (New Testament 1 Corinthians 15:20 - 22)

As we realize that we like the Savior will be resurrected, the more we live like the Savior the more we become like the Savior. John explained this asking -

"...are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is." (New Testament 1 John 3:2)

But it will not happen immediately, but line upon line, the Savior's grace upon grace as Paul told the Corinthians -

"...we all, with open face beholding as in a glass the glory of the Lord, are changed into the same image from glory to glory, even as by the Spirit of the Lord." (New Testament 2 Corinthians 3:18)

"For all things are for your sakes, that the abundant grace might through the thanksgiving of many redound to the glory of God.
16 For which cause we faint not; but though our outward man perish, yet the inward man is renewed day by day.
17 For our light affliction, which is but for a moment, worketh for us a far more exceeding and eternal weight of glory;
18 While we look not at the things which are seen, but at the things which are not seen: for the things which are seen are temporal; but the things which are not seen are eternal." (New Testament 2 Corinthians 4:15 - 18)
