How do we know that Christ's imputation is true?

The doctrine of imputation, which posits that the sins of believers were charged to Christ while His righteousness is credited to them, is supported by clear biblical revelation. In 2 Corinthians 5:21, we find that Christ was made sin for us, a statement indicating that our sins were imputed to Him. This is further affirmed in Isaiah 53:6, where it says, 'the Lord hath laid on Him the iniquity of us all.' Additionally, the New Testament consistently emphasizes that through Christ’s sacrifice, believers are justified and declared righteous. Therefore, the doctrine is not merely a theological idea but is rooted in divine revelation throughout Scripture.
