Why is the story of Cain important for Christians?

The story of Cain is crucial for Christians as it highlights the dangers of disobedience and the seriousness of approaching God without reverence. Jude 11 warns against those who 'have gone in the way of Cain,' emphasizing the urgency of contending for the faith amidst false teachings and ungodly influences. Cain's rejection of God's prescribed way of worship illustrates the broader theme of rebellion against divine order, reminding believers that true acceptance before God comes through humility and faith, not through self-styled righteousness.
