How do we know the holiness of God?

God's holiness is a foundational attribute that defines His nature. Exodus 33:20 states, 'Thou canst not see my face, for there shall no man see me and live.' This indicates the seriousness of God's holiness and the separation it causes between Him and sinful humanity. According to Exodus 34:7, God will not clear the guilty, establishing that sin has consequences that must be addressed. His holiness is not just a concept but a reality that all must acknowledge to understand God's justice and the need for atonement through Christ.
