Unconditional love

Do I believe that I surrender to God all that I own and have, that I will have a greater reward in heaven than someone who has a faith as a small part of their lives?  Maybe this way of looking things is looking for a reward to justify a way of living.  However, what if living a life of love, a life of giving ourselves away to people and to God is reward enough in itself?  What if doing it for an eternal reward is to steal from loving in the moment?  What if at the gates of paradise, someone who has surrendered their entire life to love, and someone who had faith as a part of their life were both given an equal share of the kingdom?  If this were the generosity of God, would it not be all the more worth working for or surrendering to?
