In this shiur, delivered in Tomer Devorah, Rav Burg explains why although the Aish on the Mizbeach comes from Hashem, the Kohen had to light the fire in the morning. And athough the fire comes from Hashem, we are instructed to protect it when we travel. The nature of life is engaging with suffering but a Jew is thankful for the suffering they endure because that's how we discover Hashem. It will always rain on our fire but we are assured that our fire can never be extinguished. Our job is to chop the wood and protect the fire.
