Can you elaborate on the purpose of life, and what should I do to achieve true happiness? A man's sufferings are caused by the evil in his heart like; greed, lust, pride, jealousy, etc. He finds happiness only by achieving material gains, as money heals his pains caused by his evil heart. But that happiness is only temporary, because the evil in his heart continues to grow, and that makes him greedier and hence he will never find long lasting happiness in his life. In another words, man suffers for his own evil. To find the true happiness, we must first get rid of the evil inside us. Once we have accepted Jesus as our savior, the Holy Spirit will live inside our hearts and will fill our hearts with love. Loving God is the exact opposite of evil. The more we love God, the less evil we are, and the happier we will be. Imagine a heart with no evil but only love, how beautiful would that be. Love itself is so sweet, and we should pray that lets our love spreads to all the people around us. Let us not only love God, but also love all the people around us, that would be the most beautiful and happiest life we can get. Why say life is a suffering, which in fact can be beautiful and enjoying. The two greatest commandments passed on by Jesus, 'love God and love your neighbors' are in fact the purpose of our existence, and indirectly he had taught us the secret to happiness in our earthly life. end...
