You come to life only when your soul enters your body, then only the term "life" is given. Now, when your soul leaves your body, God still owns your soul. According to your karma, you'll take rebirth again in this earth. For e.g.. If you rape someone your someone will be raped too, if you torture someone then you will be tortured too through law of karma. Life does not end after you die, it just moves on. If your soul deserves liberation, then you'll be liberated, if not you'll be casted back again. Yes, so there is meaning of GOD without life.
