Excerpt
All believers of Jesus Christ who have died in their earthly form have a new body and are living with the Lord. (2 Corinthians 5:8)

Those of us who have invited Jesus into our hearts and are still living will be changed when He returns.

"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.'"
I Corinthians 15:52-54 (KJV)
