The term probationary state or probationary time is a phrase used only by Alma in the Book of Mormon (see Alma 42:4, 10, 13). Elder L. Tom Perry of the Quorum of the Twelve Apostles described this probationary time: “The main purpose of earth life is to allow our spirits, which existed before the world was, to be united with our bodies for a time of great opportunity in mortality. The association of the two together has given us the privilege of growing, developing, and maturing as only we can with spirit and body united. With our bodies, we pass through a certain amount of trial in what is termed a probationary state of our existence. This is a time of learning and testing to prove ourselves worthy of eternal opportunities. It is all part of a divine plan our Father has for His children” (in Conference Report, Apr. 1989, 16; or Ensign, May 1989, 14).
