The Church has announced that the Mutual theme for 2019 is “If ye love me, keep my commandments” (John 14:15).
According to a letter from the Young Women and Young Men general presidencies sent to local leaders Aug. 1:
“The purpose of the yearly theme is to provide opportunities for youth worldwide to learn about, study, internalize and apply the principles taught in the scripture. Youth are encouraged to memorize the scripture, study its doctrine and act on the principles learned throughout the year.
“In addition, the theme can be used in Mutual opening exercises, as a topic for sacrament meeting talks given by youth, and to provide focus for youth activities —including camps, youth conferences and devotionals.
“Resources — including videos, music and suggestions for using the theme throughout the year — will be available to leaders at youth.lds.org and in Church magazines at the end of 2018 and throughout 2019. An email will be sent to leaders later this year when these resources become available.”
