The book of Jude is only twenty-five verses in length, but it packs a spiritual wallop Jude, the brother of James (and half-brother of our Lord Jesus), writes a message to believers about the times in which they lived. Those times are not at all that much different from the days in which we now live. Jude warns against apostasy, licentiousness, and the mockers that are destined to be part of the last days. Even during Jude's day, mocking the Lord's return had already begun. How much worse is it today, roughly 2,000 years later?
