I found this on www.gotquestions.org
I think it explains what you are asking very simply and clearly. Hope this helps.
Angels are beings created by God (Colossians 1:15-17) and are entirely different from humans. They are God’s special agents to carry out His plan and to minister to the followers of Christ (Hebrews 1:13-14). There is no indication that angels were formerly humans or anything else—they were created as angels.
Eventually, the body of the believer in Christ will die. What happens then? The spirit of the believer goes to be with Christ (2 Corinthians 5:8). The believer does not become an angel. It is interesting that both Elijah and Moses were recognizable on the Mount of Transfiguration. They had not transformed into angels, but appeared as themselves—although glorified—and were recognizable to Peter, James and John.
In 1 Thessalonians 4:13-18, Paul tells us that believers in Christ are asleep in Jesus; that is, their bodies are dead, but their spirits are alive. This text tells us that when Christ returns, He will bring with Him those who are asleep in Him, and then their bodies will be raised, made new like Christ’s resurrected body, to be joined with their spirits which He brings with Him. All believers in Christ who are living at the return of Christ will have their bodies changed to be like Christ, and they will be completely new in their spirits, no longer having a sin nature.
All the believers in Christ will recognize one another and live with the Lord forever. We will serve Him throughout eternity, not as angels, but along with the angels. Thank the Lord for the living hope He provides for the believer in Jesus Christ.
The great thing in this world is not so much where you stand,
as in what direction you are moving.
