reincarnation is going back on a different form..... parang tao ka dati and babalik ka as langgam.
in the case of john and elijah, no... its not reincarnation..
The Bible is clear that John was given his role because he came into the spirit and power of Elijah (Luke 1:17), not because he was Elijah. John was the forerunner who points the way to the arrival of Christ in the NT which was the same role that Elijah did in the OT. Also, Elijah appeared with Moses during the transfiguration. Kung si Elijah si John, malamang, hindi pwede yun, o ang makikita ng mga apostles ay si John na putol ang ulo.
Lastly, John denied that he was Elijah (john 1:19-23).
Generally, the Bible opposes reincarnation.
Anyway, kung totoo ang reincarnation, pag nauna ako. Magpaparamdam ako dito, whatever form it is....
