This is a strange concept to those who believe that knowledge is obtained by reason alone. It is often met with contempt and derision. Yet, I would argue that such persons rob themselves of the true process of gaining the kind of knowledge that turns into wisdom and which brings us closer to God. Faith, whether it be in the idea that an answer exists (scientific hypothesis) or in Christ, is an essential part of every learning endeavor.
Elder Walter F. González of the Presidency of the Seventy in the Church of Jesus Christ of Latter-day Saints spoke about what it means to learn with our hearts.
Whenever someone comes to me and says, "Yes, well I've read all your books and attended all your meetings and I still am skeptical about such and such," I feel very sad for them. They hold onto doubt as if it were a security blanket. In reality, doubt is like an anchor held fast to the bottom of the ocean while a storm threatens to capsize the ship. Cut that anchor free and allow God to teach you truth, rejecting doubts that the adversary would have you listen to. God is not an author of confusion and skepticism. He is the God of Knowledge. Whatever you ask of Him, having faith, it will be given to you.
