What does the Bible teach about the consequences of sin?

Scripture consistently warns that the wages of sin is death, as noted in Romans 6:23. This highlights the serious nature of sin, which separates humanity from God and brings about spiritual death. In context, the consequence of sin is vividly demonstrated in the lives of the Israelites, as their rebellion prompted God's disciplinary actions. Similarly, for believers who fall into sin, the Lord’s chastening is an expression of His love, as He seeks to restore them to a right relationship. This dual reality of consequences—spiritual death for the unrepentant and loving discipline for the redeemed—underlines the holiness of God and the seriousness with which He regards sin, encouraging believers to seek holiness in their lives as a demonstration of their gratitude for His grace.
