Answer: Reincarnation refers to the idea that after death the spirit of a person may come back to life on earth in another body (human, animal, or even insect).  The Bible does not teach such a doctrine. It teaches that the body of the individual is part of the identity of the person (cf. 1 Thessalonians 5:23) and that the body as well as the spirit (soul) of the individual will be redeemed (Romans 8:17-25, especially verse 23).  Animals and insects are not able to reason and exercise free will. Thus humans, created in the image of God, could never inhabit bodies of insects or animals.   Reincarnation is incompatible with the Christian doctrine of bodily resurrection (see 1 Corinthians 15). According to the apostle Paul, the bodies the dead inhabit after resurrection are the same bodies they inhabited in life, only transformed into spiritual bodies (1 Corinthians 15:53; cf. Philippians 3:20, 21).
