Its only that the language used to describe resurrection is not supportive of an afterlife, and Christians are told to deny ourselves, take up our cross, hate the works of the flesh. The main prayer of a Christian is peace on earth, good will towards all, and glory to God. Basically everything that people want to be in the afterlife for are works of the flesh. Do you like cheese? That's a desire of the flesh. That won't be part of the resurrection. Do you have a wife? You won't at the resurrection. Do you like to daydream? You won't at the resurrection. Do you smile? That's of the flesh. You won't at the resurrection. Do you have children? You won't at the resurrection.
What language are you referring to? Why do you believe that the language used to describe resurrection is not supportive of an afterlife?
It is true that Christians are told to deny themselves, take up their cross, hate the works of the flesh and pray for peace on earth, good will towards all, and glory to God, and that is a darned good idea since there will be no flesh after people die and enter the spiritual world (heaven), so it is not going to benefit anyone to be attached to the things of the flesh.
Why do you think that everything that people want to be in the afterlife for is works of the flesh? I do not believe there will be any more flesh after we die because we will be raised in spiritual bodies, as Paul said in 1 Corinthians 15:40-54, and since there will be no physical bodies there will be no sex, no food or drink, and nothing that people now enjoy doing in a physical body. However that does not preclude people seeing their children and spouses or other family and friends in the spiritual world, and they will have spiritual bodies.
Nothing human survives the resurrection...according to what I think that Jesus and Paul say. What is resurrected? Some sort of non-human divinity, not anything like a human. There's nothing desireable about an afterlife described in this way, except that you can do some good before you die.
What makes us human is our soul, not our physical body, and our soul continues to live forever. All of who we are -- our personality -- will survive the resurrection, except the physical body. The death of man is merely his soul passing from one world into another. When the soul passes from this world into the spiritual world it takes on a new form comprised of spiritual elements that exist in the spiritual realm of existence.
What is eternal life? When Jesus referred to
eternal life, He was not referring to physical life of the body. He was referring a quality of life,
spiritual life, loving God and being close to God. The soul is eternal, the body perishes. That is why Jesus said: John 6:63 It is the spirit that quickeneth; the flesh profiteth nothing: the words that I speak unto you, they are spirit, and they are life
All souls will continue to exist in the spiritual world after the body dies but not all souls will have eternal life (everlasting life). Eternal life refers to a “quality” of life, nearness to God which, according to Jesus, comes from believing in Him.
“The immortality of the spirit is mentioned in the Holy Books; it is the fundamental basis of the divine religions. Now punishments and rewards are said to be of two kinds: first, the rewards and punishments of this life; second, those of the other world. But the paradise and hell of existence are found in all the worlds of God, whether in this world or in the spiritual heavenly worlds. Gaining these rewards is the gaining of eternal life. That is why Christ said, “Act in such a way that you may find eternal life, and that you may be born of water and the spirit, so that you may enter into the Kingdom.” 2” Some Answered Questions, p. 223
“Likewise, the rewards of the other world are the eternal life which is clearly mentioned in all the Holy Books, the divine perfections, the eternal bounties and everlasting felicity….The rewards of the other world are peace, the spiritual graces, the various spiritual gifts in the Kingdom of God, the gaining of the desires of the heart and the soul, and the meeting of God in the world of eternity.” Some Answered Questions, pp. 224-225
