God is our teacher

God teaches us in our hearts. Perhaps you feel that a book or person has "taught" you as well; but the truth of the matter is that if a book or person has "taught" you it is only to point out something that God taught you in your heart, or to point out something God has tried to tell you but your heart was closed to it. In hearing or reading you find words articulating the truth that God is teaching you, and through these mediums He reaches your heart to give it His Wisdom.
