What does the Bible say about sin and its consequences?

The Bible highlights the seriousness of sin and its repercussions through various narratives, including the story of King David. In 2 Samuel 12, after David's grievous sins of adultery and murder, God sends Nathan the prophet to confront him. Nathan exposes David's actions, making him aware that his sins had not only personal repercussions but also had brought shame to God's name, provoking blasphemy among His enemies. The consequences for David were multifaceted: a public humiliation, the death of the child born from his sin with Bathsheba, and ongoing violence within his family. The passage teaches that sin is not a trivial matter and carries long-lasting effects, both in this life and spiritually.
