Sometimes we don't feel like God hears our prayers. I know this because I've felt this way lately about decisions I'm trying to make in my life. This scripture is so comforting. The key to receiving answers to our prayers is asking in faith for those things which are good -- those things that lift us and grant us the potential to lift others.
We also need to have the faith that we will receive an answer from our Heavenly Father. We have faith that our parents will answer us when we ask them a question, so why don't we place that same trust in our all-loving, all-knowing Father? Our prayers could become so much more powerful when we believe that we will receive an answer.
