How do we know the doctrine of sin imputation is true?

The doctrine of sin imputation is affirmed through various scriptural passages that elucidate how Christ, in His agony, identifies with the sins of humanity. John 12:27 is pivotal as it illustrates the depth of Christ's distress due to the burden of sin He was about to carry. The voice from heaven confirming His mission further underscores this reality—that He was sent to take upon Himself the guilt of the world, which gives believers comfort that our sins have been genuinely borne away. This foundational truth of salvation encourages Christians to cling to the assurance that Christ's sacrifice was sufficient and personal.
