That is Platonism, not Christianity. You are a soul/body composite. Your soul is not you; it is a part of you. Your body is not you; it is a part of you. We are not angels(i.e. spirits); we are mammals. We are not merely using bodies, like we drive cars. Smashing someone's car is ethically not equivalent to smashing their body. We *are* our bodies, though not only our bodies, because our soul is part of us as well.
What scriptural evidence do you have that would lend us to believe that we're stuck with this thing for an eternity?
First, consider passages that state that we material beings.
"Then the LORD GOD formed man of dust from the ground, and breathed into his nostrils and breath of life; and man became a living being." (Gen 2:7)
"Remember that you molded me like clay. Will you now turn me to dust again?" (Job 10:9)
"You turn men back to dust, saying, "Return to dust, O sons of men." (Psalm 90:3)
"For he knows how we are formed, he remembers that we are dust." (Psalm 103:14)
"But your dead will live; their bodies will rise. You who dwell in the dust, wake up and shout for joy. Your dew is like the dew of the morning; the earth will give birth to her dead." (Isaiah 26:19)
"Multitudes who sleep in the dust of the earth will awake: some to everlasting life, others to shame and everlasting contempt." (Dan 12:2)
Second, the doctrine of the resurrection of the body does not fit with Platonism. If we are spirits, then being thrust back into bodies is like being thrown back into prison. But the doctrine of the resurrection of the body says that our bodies are good, that they are part of who we essentially are, and that we are not complete until they are restored to us. The doctrine of the resurrection of the dead is not a doctrine about a "re-creation" of the body. It is a *resurrection* of the body, a bringing back to life of this body.
If you want to know of Scripture verses concerning the resurrection of the body, consider the following:
"Do not be amazed at this, for a time is coming when all who are in their graves will hear his voice 29and come out—those who have done good will rise to live, and those who have done evil will rise to be condemned" (John 5:28-29)
"Listen, I tell you a mystery: We will not all sleep, but we will all be changed— 52in a flash, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, the dead will be raised imperishable, and we will be changed." (1 Cor 15:51-52)
"For the Lord himself will come down from heaven, with a loud command, with the voice of the archangel and with the trumpet call of God, and the dead in Christ will rise first." (1 Thess 4:16)
