Spencer W. Kimball

“We mortals who now live upon this earth are in our second estate. Our very presence here in mortal bodies attests the fact that we ‘kept’ our first estate. Our spirit matter was eternal and co-existent with God, but it was organized into spirit bodies by our Heavenly Father. Our spirit bodies went through a long period of growth and development and training and, having passed the test successfully, were finally admitted to this earth and to mortality” (Teachings of Presidents of the Church: Spencer W. Kimball, p. 3-4).
