It happened that I opened the Bible to seek for enlightenment and the first few lines struck me. . .

Psalms 53:1                  Fools say to themselves, ''There is no God"   .
                         They are all corrupt, and they have done terrible things;
                                      there is no one who does what is right.

               Indeed, there were some points of my life when I have doubted the existence of God. Many times, I wondered if my prayers really reached the heavens or just disappeared through thin air. People always hurt me, even my friends; I can't feel that my family is really proud of me; and everyone around me, I don't know how to trust them. I simply don't know why I exist!

               I finally asked God to hurt those who hurt me, punish them, and let them fall on their knees.
Yet, nothing happened. Totally none.

               Later, as I've known more about God, I realized that I was wrong. Absolutely wrong! He isn't a God of Vengeance, He is a God of Forgiveness, of Mercy and Compassion. He wouldn't want His children hurt and so I was a fool to think that He wasn't real. He was indeed like the air -- invisible and not felt most of the times, but still supports my whole life. I know without air, I could've died; and without God, I never could've even lived.
