In his book, Celebration of Discipline, Richard Foster discusses the importance of solitude. He explains that it is through solitude that we are able to connect with God and hear His voice. Foster says that when we are alone, we are able to focus on God and be still in His presence. This allows us to hear His voice more clearly and receive His guidance for our lives. Foster believes that everyone needs some time alone with God each day in order to grow closer to Him.
