Perspicuity
The Word of God is necessary and profitable not only for beginners and little ones but also for the most advanced and spiritual believers here upon earth. It is a brook from which a lamb may drink and an ocean in which an elephant can drown. He who is of the opinion that he has advanced beyond Scripture is a fool. He gives evidence that he is ignorant of the spirituality of the Word as well as ignorant of himself
