is coming back to this world again, then it's wrong. The concept if base on the Holy Book is the eternal life as promised to certain people. All dead will be resurrected and all those who will be still alive on the second coming will be judge accordingly.

Those who did good (in His eyes) will live in Heaven while those who did bad (in His eyes) will suffer in Hell eternally.

It depends on one's conviction what he will do with his life here NOW, in the first place, you will never know (unless you believe in the Scriptures)what awaits you after death.
