The Church has announced that the Mutual theme for 2017 is James 1:5–6:

“If any of you lack wisdom, let him ask of God, that giveth to all men liberally, and upbraideth not; and it shall be given him. But let him ask in faith, nothing wavering. For he that wavereth is like a wave of the sea driven with the wind and tossed” (emphasis added)

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.

The theme may also be used to enrich Mutual opening exercises, as a topic for sacrament meeting talks by youth, or to provide focus for youth activities, including camps, youth conferences, and devotionals. Leaders are encouraged to emphasize any of the principles taught in this verse to help meet the needs of the youth they serve.

Resources for introducing the theme, including videos and music, will be available online by the end of 2016. Additional materials supporting the theme will be made available in Church magazines and on LDS.org throughout 2017.
