In our domain universe, within God's spiritual universe. We vessels encompass within us a soul. Like a blank CD, we live life, inscribing upon our souls all of our life. God, gave man free will of heart and volition. So, man sojourns his years upon earth. Collecting deeds upon one's soul.
God, created GOOD & EVIL upon earth. Like a fullers fire, refining the slag from the gold. Our soul, through our volition, gathers slag[evil] or gold[good]. This soul on judgment day will be judged by God. The good God will retain and the evil banished.
If you died today, are you absolutely certain that you would go to heaven? You can be! TRUST JESUS NOW
