Revelation As a Process of Sifting and Winnowing

“The Lord uses imperfect people…He often allows their errors to stand uncorrected. He may have a purpose in doing so, such as to teach us that religious truth comes forth “line upon line, precept upon precept” in a process of sifting and winnowing similar to the one I know so well in science.”
