confusion

So I teach the 2nd and 3rd Sunday lessons for the Eldes quorum in church each month. Today I was just finishing up my lesson prep about the final judgement twe were going to act out the judgement) when I figured out that I was actually teaching about the millenium instead. I had looked at that lesson earlier in the week and thought I had already taught it. Turns out I had just read it a couple of times to get ready to teach. Oops. So I changed it up and figured out comparisons between aspects of millenial life and how we can bring rhat into our daily lives today. And next week I'll be extra ready for my lesson.
