Kevin DeYoung on the Serious Problem of Prayerlessness

Here's an excerpt from Kevin's good post on the importance of prayer:

Prayerlessness is the measure of our unbelief. We don’t really believe that God answers prayers. We don't really believe that we have not because we ask not. We don't really believe that God can do more than we ask or imagine. True, God doesn't need to hear from us, but he ordained prayer so that we might be convinced of our need for him and he might be glorified in answering our prayers.
