When a man named Jude sat down one day in the first century to record some thoughts about the Christian life, he suddenly changed his mind. Instead of presenting a calm, calculated explanation of our walk with Christ, he unloaded a blistering exposé of apostasy, exhorting his readers to “contend earnestly for the faith” (Jude 1:3). Because God led Jude to change his message, today we have this postcard of helpful guidelines on how to stand firm against the tempting trends of our times. Unlike many today who tolerate heresy to keep the peace, Jude demonstrated clearly that the battle for truth demands our effort.
