What does the Bible say about the relationship between sin and death?

In Genesis, we learn that sin is never an isolated act but has far-reaching consequences. Adam's sin brought death not just to himself but to all humanity, affecting his family and subsequent generations. The principle that 'the wages of sin is death' is foundational, highlighting the serious nature of disobedience to God. This effect of sin is vividly demonstrated in Genesis 4 with Cain and Abel, where Cain’s sin culminates in the death of his brother Abel, showcasing the devastating fruit of sin in a familial context.
