The Bible tells us that there are two possibilites concerning our eternal destiny.
Every person has a body and within that body is a soul, and that soul is eternal.
At the time of death, the body goes into the grave and returns to dust, but the soul lives eternally in either one of two places. One place is described as a place of everlasting torment separated from God in the lake of fire. In verse 10, the lake fo fire is described as a place of torment that lasts day and night forever and ever. The other place is described as a place of never-ending joy in the presence of God in Heaven. It is a place where the glory of God will be the light, and those that are there will reign with God forever and ever.
