Personal devotion best begins with a quiet spirit. Anyone's spirit can be agitated. Often, to calm our human spirit requires divine intervention. If your spirit is restless. Rolling and tumbling moving about like the sea during a storm, start your personal devotion by taking your disquiet to Jesus.
