Surprisingly, I already had the chance to teach this lesson in my own Relief Society class last week as our Stake decided to combine lessons 1 and 2. As a guinea pig, I was able to learn a few things that worked well in this lesson and am happy to pass them on to you.
We Are Children of Our Heavenly Father
I was really pleased to see this thoughtful question the manual posed at the start of the lesson: What do scriptures and latter-day prophets teach us about our relationship to God? Possible ideas you may want to discuss in answer to the question:
* Modern revelation teaches that our God is a literal parent. How is having a relationship with a Heavenly Parent different from having a relationship with other notions of God (Heavenly King, Judge, Lord, Creator, Almighty)? You may also want to read the Joseph F. Smith quote here that our “spirit[s] [were] begotten and born of heavenly parents and reared to maturity” in the preexistence. What are the kinds of things you imagine our heavenly parents would have wanted to impress upon us to prepare us for mortality?
