You ask your parents for the car keys and they say “No. You can’t have them. It’s not a good idea.” Do you say, “Okay, so then you don’t exist?”
Well, a person can say the words, but of course they will exist just the same.
Sometimes, Hashem answers our requests and sometimes He doesn’t. He knows more than we do, and if He says no, then there’s a reason for it. So to conclude that He isn’t there because we didn’t get what we wanted is silly.
“No” is the answer.
Don’t stop praying because things didn’t go the way you wanted. He’s there, listening.
~ Rav Gav Friedman
