Important first thought: I don't want to promote any kind of "activism" at church...except of course Christian activism.
With that out of the way, I want to remind everyone of some great opportunities to discuss Earth Stewardship in upcoming Sunday School classes. Lesson 22 The Word of Wisdom "A Principle with a Promise", and lesson 38 "In Mine Own Way" both include some material regarding with Earth Stewardship.
Lesson 22 includes D&C 59:17-20 as source material. This lesson will probably be taught sometime in May.
Lesson 38 includes D&C 104:13-18 as source material. This lesson will probably be taught sometime in October. BTW, The late Elder Maxwell had some interesting words regarding these scriptures.
If you find it appropriate,
and if it fits into the content of your class discussions,
and if it adds to the spirit of your class,
and if it brings glory to God,
then please consider sharing your feelings about Earth Stewardship during one or both of these lessons.
Final thought: Please don't abuse this as a chance to prove a point or advance a political agenda. Nobody likes it when people abuse church meetings for their own purposes.
