Let us give ourselves to be intercessors. Let us cry with importunity to God when we see people who need help, when the spirit of compassion stirs within us, when we feel our own powerlessness to help, or when we see obstacles in the way of our getting an answer. God alone can help. And in answer to our prayers, He will help.
