Once you truly experience God's grace, it's hard to fathom regarding it as a license to sin. Yet, this is exactly the kind of behavior that Jude condemns in a letter spanning a mere 25 verses. The danger he warns against is a common one, really: The church ceases being watchful and instead becomes passive. But it's precisely when this happens that false teachers creep in and wreak havoc, taking grace for granted and twisting sound doctrine. Not one to mince words, Jude reserves his most scathing rebuke for such people—their fate, he says, is the gloom of utter darkness. So what's a faithful church to do when passivity simply isn't an option? Contend with all their might for that which is unimaginably precious: the faith.
