How do we know that God's standard of judgment is immutable?

The immutability of God's standard is rooted in His nature as a holy God who does not change. Malachi 3:6 declares, 'For I am the Lord, I change not; therefore ye sons of Jacob are not consumed.' This means that God's requirements remain constant across generations and cultural contexts. He judges all people with equality, holding everyone to the same standard of perfect righteousness. The assurance we have as believers is that this unchanging standard drives us to Christ, who met the requirements of the law perfectly on our behalf.
