How do we know that Christ's atonement satisfies God's law?

The assurance of Christ's atonement satisfying God's law is rooted in Scripture, particularly in Colossians 2:14, which states that He 'blotted out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to His cross.' His sacrifice not only fulfilled the demands of the law but removed the condemnation that stood against humanity. This is a foundational aspect of Reformed theology, highlighting that through the lens of Christ's finished work, believers are seen as perfect, with no further need for the law to accuse them. As stated, 'Who shall lay anything to the charge of God's elect? It is God that justifieth.'
