Gendou,
Why did you completely overlook the context of the first verse you quoted? We will have spiritual bodies:
1Co 15:35 But someone will ask, "How are the dead raised? With what kind of body do they come?"
1Co 15:36 You foolish person! What you sow does not come to life unless it dies.
1Co 15:37 And what you sow is not the body that is to be, but a bare kernel, perhaps of wheat or of some other grain.
1Co 15:38 But God gives it a body as he has chosen, and to each kind of seed its own body.
1Co 15:39 For not all flesh is the same, but there is one kind for humans, another for animals, another for birds, and another for fish.
1Co 15:40 There are heavenly bodies and earthly bodies, but the glory of the heavenly is of one kind, and the glory of the earthly is of another.
1Co 15:41 There is one glory of the sun, and another glory of the moon, and another glory of the stars; for star differs from star in glory.
1Co 15:42 So is it with the resurrection of the dead. What is sown is perishable; what is raised is imperishable.
1Co 15:43 It is sown in dishonor; it is raised in glory. It is sown in weakness; it is raised in power.
1Co 15:44 It is sown a natural body; it is raised a spiritual body. If there is a natural body, there is also a spiritual body.
....
1Co 15:53 For this perishable body must put on the imperishable, and this mortal body must put on immortality.
Jesus had this type of body, with which he could walk into a room with a closed, locked door:
Luk 24:37 But they were startled and frightened and thought they saw a spirit.
Luk 24:38 And he said to them, "Why are you troubled, and why do doubts arise in your hearts?
Luk 24:39 See my hands and my feet, that it is I myself. Touch me, and see. For a spirit does not have flesh and bones as you see that I have."
Luk 24:40 And when he had said this, he showed them his hands and his feet.
Luk 24:41 And while they still disbelieved for joy and were marveling, he said to them, "Have you anything here to eat?"
Luk 24:42 They gave him a piece of broiled fish,
Luk 24:43 and he took it and ate before them.
Joh 20:19 On the evening of that day, the first day of the week, the doors being locked where the disciples were for fear of the Jews, Jesus came and stood among them and said to them, "Peace be with you."
