This is the song the Primary is learning this month for the Primary program this fall. I changed "Father" to "Parents." I also changed "The Lord" to "My Parents." The syllables don't line up, but it's not too hard to fit that extra one in.
My Parents gave me a temple to live within on earth.
Once in Heaven I was spirit, but I left my home at birth.
I’ll make my temple brighter; I’ll keep my spirit free.
My body is the temple my Parents gave to me.
If I keep my body clean and pure and habit-free,
I may in my Parents' temple claim blessings promised me.
On resurrection morning, I’ll take my body bright
And in celestial glory forever live in light.
