Lesson 1 of the Gospel Principles manual is called, "Our Heavenly Father". The original lesson can be found online, here.
We are going to be using this manual for our FHE lessons this year. With few exceptions, all of the lessons are short and they are easy to adapt to your individual needs.
I like the fact that each lesson is about a basic Gospel principle: Our Heavenly Family, Scriptures, Prayer, Prophets, Priesthood, etc.
I planned to go through the lesson and ask the main questions. I asked the first one: "How do you know that we have a Heavenly Father?"
My children then directed the rest of the lesson from there. We ended up with a great question/answer discussion about Heavenly Father and about the creation. I was able to use several of the scriptures the lesson suggested to guide some of our discussion, even if I didn't use the entire lesson as I had planned to do. There were also several questions posed that we did not have answers to, but that experience is a fantastic opportunity to talk about faith and how we don't always have answers, but we trust Heavenly Father.
It turned into one of the best lessons we've had in a long time. It was also a special time to see what our children are learning and remembering and, more importantly, what spiritual things they are wondering about.
We closed by talking about the things we could do to come to know Heavenly Father better and we resolved to be better at family prayer and family scriptures.
