"And you shall know them by their works..." Or something to that effect, I can't quite remember after all these years. Basically, you show your uncoditional love for your fellow man by the way you treat others, and the way you live your life. If you produce beautiful works, full of love, designed to help and facilitate joy....you are doing Gods work. Most of all, learn to love yourself as well. I believe it was Peter who said that you cannot do well by others if you have not first taken care of yourself (paraphrasing, of course). Point being, make sure to take time to enjoy the life that you have, use it to fulfill the promises of Christ on this side of whatever "afterlife" you believe in. Why do something solely to get into a "heaven" or "paradise", how selfish is that? Do things because you love your fellow man, because you are humble, and do not shout your works from the street corners like the Pharisees of old. It is an amazing thing when you learn how to truly love. It makes miracles happen, you can do the impossible all of a sudden, you can make yourself everything you've ever wanted to be. Most of all, you learn true compassion and empathy, not through judgmentalism, but through unconditional love. We all know the scripture:
Love is patient, love is kind, Love is not jealous; love does not brag, is not arrogant, does not act unbecomingly; it does not seek its own, is not provoked, does not take into account a wrong suffered, does not rejoice in unrighteousness, but rejoices with the truth; bears all things, believes all things, hopes all things, endures all things.
