Apostasy is in our nature, and it can creep into the church very quickly. Jude wrote his epistle to put apostasy in check, reminding us that while God delivered His people from Egypt, He destroyed that first generation for their faithlessness. Even after the people saw God's miracles of deliverance in Egypt, they were quick to turn from Him and forgot what He had done. We need this wake-up call to be vigilant and keep contending for the faith.
