Not necessarily a Christian idea.
It is, after all, a truism that you learn best from your mistakes. After all, a success might or might not tell you what you did right. A mistake WILL tell you (at least in part) what you did wrong.
Applied to life in general, this truism leads to some suffering and potential for harm. The burned hand teaches best ⌠but some burns are worse than others. Simply learning to drive a car is a Darwinian experience in Americaâthe chances of dying or suffering serious injury in a car driven by someone 16-21 are vastly higher than those of, say, 29-40. A friend of mine, who recently passed after complications, was almost completely paralyzed from the neck down after a simple swimming accident at age 16.
Life is Darwinian. Our choices can, and often do, determine our fates. Bad choices = bad fate OR challenges to overcome (often, both).
This isnât a Christian idea. They simply adopted it as Godâs motis operandae.
