Are You There, God? It’s Me, Trina
To me, belief in God means that I believe in a creator, who brought about this world and all the creatures on it, including myself.
To me, believing in God means that I have a constant companion, so-to-speak. Even when my friends leave me lonely, I know God is here with me and He'll listen to what I have to say, even if it's not so good. I try to hear back, but am never sure if it's Him or not talking to me.
Believing in God, to me, means that when I need a doctor, I have the best one. When I need a comforter, He is there for me to cry and wail to. When I need an advisor, He gets the relevant knowledge to me.
When I say I "believe in God", I don't just mean that I believe in some man in the sky; I mean there's someone, a spirit, with whom I have a relationship and that's the most important thing to me.
