“Teachings for Our Time,” Ensign, May 2015, 140
From May 2015 through October 2015, Melchizedek Priesthood and Relief Society lessons on fourth Sundays should be prepared from one or more talks given in the April 2015 general conference. In October 2015, talks may be selected from either the April 2015 or the October 2015 general conference. Stake and district presidents should choose which talks will be used in their areas, or they may delegate this responsibility to bishops and branch presidents.
Those attending fourth-Sunday lessons are encouraged to study the selected talks beforehand. Conference talks are available in many languages at conference.lds.org.
