One of the biggest differences between children and adults is the ability to control our thoughts, attitudes, and emotions as grownups. We rarely see a 40 year-old having a temper-tantrum! Yet in this verse, Paul is exhorting us to be child-like regarding evil. Now he doesn’t mean that we should be ignorant, naive or easily exploited by evil, but rather, we should be innocent in our motives and thinking about it…not allowing rationalization or deception to creep into our mindset. This comes, Paul says, from growing up into spiritual maturity and taking all of our thoughts captive to make them obedient to Christ. (II Corinthians 10:5)
