Christ rose from the dead in the body that He died with, but, when He arose, it was with a glorified body - a body that would never die again. Jesus did not leave this body when He left the earth. He will return to earth in that same body.
At His return, all who are waiting for Him in faith will share with Him a glorified, forever body. We won't become someone different or an angel. This body will be us, our body, but new, restored, perfected, glorified and fit for eternity in God's presence.
