No one is ever useless to God. No one who can pray is ever useless. There are many people to perform the needed activities, but too few to take the time for prayer. I suppose the hardest thing about being an invalid, about being “useless,” is that it is much harder to receive help than to give it. It is much harder to be still than to be active. That is why it is important to learn how to be a gracious receiver as well as a gracious giver.
