Someone said to me this week that God doesn't always answer your prayers, no matter how hard you pray.
I'm not sure how I feel about that sentiment. I'm not an overly religious person but I do believe He is listening when you talk to Him. Maybe He is answering your prayers but not in the way you want Him to. Maybe He is giving you something better than what you were praying for.
But if I had a sick child or loved one and I prayed night and day for my child or loved one to recover only to have the opposite happen, I might feel the way the person I quoted above does.
