What an elusive word “immortality”! An impossibility. How could mortal man put on immortality? Death is still an impossible impasse today. The best scientists together could not prolong life beyond the limit of 120 years old given in Genesis 6:3 And the LORD said, My spirit shall not always strive with man, for that he also is flesh: yet his days shall be an hundred and twenty years.
The time when the church of Jesus Christ shall be taken to heaven (born-again believers both dead (asleep) and the alive) will be preceded by a trumpet sound. The Apostle Paul called it “the last trump”.
The Bible predicts in the coming future, a coming instant where born-again believers in the Lord Jesus Christ shall put on a glorious and incorruptible body that is fit for heaven and shall be ushered to meet our Lord in the heavens. Theologians call this the rapture of the church where the believers are caught up to heaven. Just as Enoch in the book of Genesis was taken to heaven bodily.
There is a time of change that will take place for all who sleeps in the Lord. And the Apostle Paul is signalling to the saints to “behold”. He urges them to see the mystery of God’s resurrection power unveiled to reverse the sting of death upon all who have died in Christ.
This earthly body is not fitted for dwelling in heaven. This is the meaning of the statement “flesh and blood cannot inherit the kingdom of God.” We shall be given a heavenly body fitted for our heavenly home when Jesus returns. This is the believer’s blessed hope.
God’s work of redemption for fallen men is meant to rescue them from hell to heaven. The earthy, the man that lives upon earth, that is cursed to an unavoidable death, has a reprieve. And the earthy is starkly contrasted with the heavenly. The curse of the earthy is contrasted with the blessing of the heavenly.
Every believer has this hope that his mortal body will return to earth but God will remake new an immortal body. This immortal body is described as spiritual and heavenly. It is a body that is fitted for glorious, heavenly living.
The first Adam became a living being when God breathed life into him as recorded in Genesis 2:7 And the LORD God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul.
The contrast is made to highlight the glory of the resurrection body of the saints at the last day. He uses the words “incorruption, glory, power, spiritual body” to describe the glorified body given to the believer when the Lord returns.
The beginning of the human soul is at physical birth. Born into this world after the fall of Adam and Eve, man is plagued with the disease of sin that brings to him misery, suffering and finally death and then judgment in hell-fire. But God in His mercy did not leave men to eternal misery and torment.
