I talk to God every day, and I know he listens, and when he talks to me I make sure I listen, basically because he IS God and I am a mere mortal, if I get angry with him he will laugh at my temper tantrum, whereas if I ever angered him he is so powerful he could do anything he likes to me.
So my question to you is, how do you know he dosn't listen? don't forget he hears everyone, but things are done in his time and not ours.
