This sermon discusses the armor of God from Ephesians 6:10-20, comparing it to the Space Shuttle Columbia disaster where a small breach in the heat shield led to catastrophic failure. The message emphasizes that Christians are in a spiritual war against a methodical enemy (the devil) who seeks to destroy us. The pastor outlines four realities of spiritual warfare: we have an adversary, we are in a war, we have a solution (the full armor of God), and we have a purpose (to share the gospel).
