(The Proclamation on the Family, 2nd paragraph)
That's kind of a long sentence. Often, when I read sentences that are that long, I either break it down into smaller ideas so that I can wrap my head around them, or just give up altogether and move on to another sentence. In this case, I'll choose the "break it down" route.
So, in my opinion, this sentence says:
1. There was a place where we all lived before this life.
2. I, as well as my spirit brothers and sisters knew my Father in Heaven and worshiped him.
3. We (my spirit brothers and sisters and I) accepted a plan that Heavenly Father presented to us.
4. The plan included a way for us to get a physical body, and to have some experiences on earth.
5. Those experiences would help us on the road to perfection.
6. Ultimately, those experiences could (depending on the decisions we would make on earth) allow us to obtain eternal life.
As I break it all down, there are some marvelous ideas contained in that sentence. I love to think about our Father in Heaven presenting this plan to us, and then allowing us to choose, rather than just rounding us all up around Him, and saying, "Okay, this is how it's going to be."
I love knowing that the experiences I'm having here on earth aren't just random occurrences in my life, but have been and continue to be given to me specifically--a kind of "individualized coursework" if you will.
I love knowing that Heavenly Father and His son Jesus Christ have made it possible for me to live with them and with my loved ones again, and forever.
