This sermon is the second in an Advent series entitled “Spanning the Space Between.”
Isaiah 11:1-10, Matthew 3:1-12
A few years back, Jennette arranged a camping trip to Lake Tahoe for our church. It had been awhile since I’d been there, and I was surprised and saddened by the sight of so many dead pine trees. Instead of seeing one long swath of green over the mountainsides, there were whole chunks of forest that were brown with dead trees, and other chunks that were a mottled mix of green and brown. In fact, tree die-off is happening all over our western forests, from the Yukon all the way to Mexico.
Why is this happening? On the surface, the culprit is drought and insects, particularly the bark beetle. As our climate warms, winters shorten and droughts in western forests intensify, weakening trees, which then makes them easy prey for the beetles. But the real culprit may actually be that there’s not enough fire. Scientists and forest managers now believe that decades of suppressing forest fires in the interest of protecting private property has resulted in forests that have too many trees in them. It used to be that fires would happen about every 10 to 15 years, which kept the forest from getting overcrowded. Such forests could better sustain periods of drought because there wasn’t so much competition for water and other resources. But suppressing fire produces too many trees that are then all more susceptible to drought and bark beetles. In addition, fire suppression paradoxically produces bigger and more violent fires because there’s so much more fuel to burn in an overcrowded forest. We need fire. It’s destructive; it’s dangerous; it’s hard to control; it’s scary. But we need it.
