Reincarnation is the teaching that after death, the soul goes to a holding place and then enters a new human body.  Some even believe we are incarnated into animals, plants , and even inanimate objects. This cycle continues over and over again for thousands of years until the person supposedly learns what he/she needs to be learn, and then the reincarnation process ceases.
 
Belief in reincarnation is a central tenet within the majority of Indian religions, such as Hinduism, Sikhism, and Jainism. In the west, some New Age movements, along with followers of spiritism also adhere to reincarnation. For the Christian, however, there can be no doubt: reincarnation is unbiblical and must be rejected as false. If reincarnation is true, then there is no Day of Judgment, no need for the Cross and no need to trust in Christ.
