What does the Bible say about forgiveness in John 8?

In John 8, we see Jesus confronting a situation where a woman caught in adultery was brought before him. The law stated that she should be stoned, presenting a dilemma between justice and mercy. When Jesus asked those without sin to cast the first stone, he demonstrated that all have sinned and thus are guilty. His response to the woman, 'Neither do I condemn you; go and sin no more,' reveals how he embodies forgiveness while upholding his righteous nature. This act exemplifies the belief that God can justly forgive sin without turning a blind eye to it, fulfilling both justice and mercy through Christ's ultimate sacrifice.
