What does the Bible say about the age of accountability?

The concept of an age of accountability is not found in Scripture. Instead, the Bible teaches that all humanity, from the moment of conception, is in a state of sin due to original sin. David, in Psalm 51:5, acknowledges this reality by stating, 'In sin did my mother conceive me.' This foundational truth indicates that we are deemed guilty before God from the very beginning. Therefore, the issue isn't when we become accountable but rather our inherent nature as sinners needing redemption through Christ.
