Last night at the Sunday Night Thing Rev. Grant Odhner gave a talk about discouragement. He focused on the story of the bronze serpent from Numbers 21:4-9 and talked about how when we're discouraged it's often because we no longer feel delights in higher things (the people loathe the manna) and so we try to make up for it by finding other things to make us feel good (the Lord sends fiery serpents that bite the people). Maybe that doesn't sound all that compelling the way I put it but it really resonated with my experience of discouragement and I really liked Grant's explanation of how the Lord healed the people from the serpents' bites. If you want to know what it is you'll just have to listen to the talk.
During the talk Grant brought in selections from Arcana Coelestia 995 and 997 and John 3:1-17, where Jesus refers to the story from Numbers.
