At the rapture, God will give Christians glorified bodies, resurrect Christians in the 3rd heaven to life, and take Christians on Earth to the 3rd heaven.
1 Corinthians 15:51-54: Behold, I shew you a mystery; We shall not all sleep, but we shall all be changed,
In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.
For this corruptible must put on incorruption, and this mortal must put on immortality.
So when this corruptible shall have put on incorruption, and this mortal shall have put on immortality, then shall be brought to pass the saying that is written, Death is swallowed up in victory.
Christians will receive glorified bodies, which will be prepared to spend eternity with God. Glorified bodies will be free from death and sin.
John 14:2-3: In my Father's house are many mansions: if it were not so, I would have told you. I go to prepare a place for you.
And if I go and prepare a place for you, I will come again, and receive you unto myself; that where I am, there ye may be also.
The 3rd heaven is large enough to house all Christians. At the rapture, Jesus Christ will descend to take Christians on Earth the 3rd heaven.
1 Thessalonians 4:16-17: For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first:
Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord.
Christians who are physically dead will be resurrected to life; their bodies will be glorified and reunited with the soul and spirit. Christians who are physically alive will never die, but ascend to the 3rd heaven with their glorified bodies.
