How do we know the doctrine of Christ's innocence is true?

The truth of Christ's innocence is established through the Scriptures, which declare that He is completely righteous, undeserving of the accusations laid against Him. For example, in John 8:46, Christ challenges those around Him by asking which of them can convict Him of sin. This lack of any just accusation reinforces the scriptural affirmation that He is our sinless substitute. The paradox of the gospel, wherein Christ bears our sins and is yet innocent, is confirmed by how He pleads His cause before the Father, ensuring that those who are in Him can likewise stand before God with confidence, as His righteousness is imputed to them.
