Is Calling Evil a Mystery a Cop-Out?

God looked at his finished creation and pronounced it "very good" (Genesis 1:31). And yet within a single chapter, a serpent already hostile to God is standing in that very good world, ready to tempt. Genesis 3 tells us exactly how evil entered human experience. It never once tells us why a creature already present in an unspoiled creation was already bent toward rebellion.
That gap is not evasion; it is where the text itself stops speaking, and stopping there is a form of honesty rather than a cop-out. The scattered biblical references to a fall among the heavenly beings — Isaiah's taunt against the king who said "I will ascend into heaven, I will exalt my throne above the stars of God" (Isaiah 14:13), Ezekiel's oracle against the corrupted guardian in Eden (Ezekiel 28), Jude's brief mention of angels who "did not keep their proper domain" (Jude 6), Peter's reference to angels "cast down to Tartarus" (2 Peter 2:4), and John's vision of the ancient serpent and its angels being cast down (Revelation 12:7-9) — describe the fact and the consequences of a supernatural rebellion. None of them supply an account of its ultimate cause. And there is a reason for that missing piece, not just an absence: any explanation offered for a first sin functions logically as an excuse. A "sufficient reason" for that first rebellion would mean the choice was never actually free — it would be self-originated evil dressed up as something caused from outside, which is a contradiction. Genuine freedom, by definition, includes a first choice that cannot be fully accounted for by anything prior to it.
So evil is best understood not as a piece of the puzzle waiting to be rationally slotted into a complete picture of reality, but as an intruder — something with no rightful place in a "very good" creation, to be resisted now and finally expelled later rather than explained away. Refusing to manufacture a false answer where Scripture gives none is not weakness. It is fidelity to what has actually been revealed, trusting that "the secret things belong to Yahweh our God" (Deuteronomy 29:29) while what has been revealed remains ours to obey.
