How do we know that sin must be paid for?

The necessity of sin being paid for is established in scripture, notably in Ezekiel 18:20, which specifies that 'the soul that sins shall die.' This underscores the weight of sin and the justice of God that demands satisfaction for wrongdoing. In Romans 6:23, we see that 'the wages of sin is death,' reinforcing the idea that sin incurs a penalty that must be addressed. However, the good news of the gospel is that Jesus Christ provides this payment through His death on the cross, fulfilling the requirement of justice to enable our justification. Therefore, understanding the debt incurred by sin is crucial, as it leads us to appreciate the sacrificial work of Christ, who became our substitute and paid that debt in full.
