The Resurrection of the Dead
Our bodies will be raised physically and materially. Our souls will be reunited with our transformed physical bodies, brought back to life from the dead.
First, simply to speak of a "resurrection" of the dead is to imply physicality:
For in the resurrection they neither marry, nor are given in marriage, but are as the angels of God in heaven. But as touching the resurrection of the dead, have ye not read that which was spoken unto you by God, saying, I am the God of Abraham, and the God of Isaac, and the God of Jacob? God is not the God of the dead, but of the living. (Matthew 22:30-31)
...for recompense shall be made thee at the resurrection of the just. (Luke 14:14)
In a moment, in the twinkling of an eye, at the last trumpet: for the trumpet shall sound, and the dead shall rise again incorruptible: and we shall be changed. (1 Corinthians 15:52)
For the Lord himself shall come down from heaven with commandment, and with the voice of an archangel, and with the trumpet of God: and the dead who are in Christ, shall rise first. Then we who are alive, who are left, shall be taken up together with them in the clouds to meet Christ, into the air, and so shall we be always with the Lord. (1 Thessalonians 4:16)
Second, Philippians 3:20-21 teaches us that Christ's resurrection body is the pattern of our resurrection body:
But our conversation is in heaven; from whence also we look for the Saviour, our Lord Jesus Christ, Who will reform the body of our lowness, made like to the body of his glory... (Philippians 3:30-21)
We know that Christ was raised in a physical body because the disciples ate with Him after the resurrection:
Not to all the people, but to witnesses preordained by God, even to us, who did eat and drink with him after he arose again from the dead; (Acts 10:41)
We know that Christ was raised in a physical body because the disciples touched Him.
And behold Jesus met them, saying: All hail. But they came up and took hold of his feet, and adored him. (Matthew 28:9)
Then he saith to Thomas: Put in thy finger hither, and see my hands; and bring hither thy hand, and put it into my side; and be not faithless, but believing. (John 20:27)
Also, Jesus outright declared that His resurrection body was physical and touchable:
See my hands and feet, that it is I myself; handle, and see: for a spirit hath not flesh and bones, as you see me to have. (Luke 24:39)
This same God hath fulfilled to our children, raising up Jesus, as in the second psalm also is written: Thou art my Son, this day have I begotten thee. And to shew that he raised him up from the dead, not to return now any more to corruption, he said thus: I will give you the holy things of David faithfull. And therefore, in another place also, he saith: Thou shalt not suffer thy holy one to see corruption. For David, when he had served in his generation, according to the will of God, slept: and was laid unto his fathers, and saw corruption. But he whom God hath raised from the dead, saw no corruption. (Acts 13:33-37).
Since Christ's resurrection is the pattern of our resurrection, we will therefore be raised in a physical body as well.
Third, Romans 8:21-23 speaks of waiting for "the redemption of our bodies":
Because the creature also itself shall be delivered from the servitude of corruption, into the liberty of the glory of the children of God. For we know that every creature groaneth and travaileth in pain, even till now. And not only it, but ourselves also, who have the firstfruits of the Spirit, even we ourselves groan within ourselves, waiting for the adoption of the sons of God, the redemption of our body. (Romans 8:21-23)
Our bodies are not going to be thrown away. They are going to be renewed, restored, revitalized.
Fourth, Jesus speaks of the resurrection as involving the coming forth of individuals out of their tombs, which clearly indicates a physical concept of the resurrection:
Wonder not at this; for the hour cometh, wherein all that are in the graves shall hear the voice of the Son of God. And they that have done good things, shall come forth unto the resurrection of life; but they that have done evil, unto the resurrection of judgment. (John 5:28-29)
Fifth, the Old Testament speaks of the resurrection as being physical:
And many of those that sleep in the dust of the earth, shall awake: some unto life everlasting, and others unto reproach, and shame. (Daniel 12:2)
I know that my Redeemer liveth, and in the last day I shall rise out of the earth. And I shall be clothed again with my skin, and in my flesh I will see my God. Whom I myself shall see, and my eyes shall behold, and not another: this my hope is laid up in my bosom. (Job 19:25-27)
