How do we know God's view of humanity is accurate?

The accuracy of God's view of humanity is confirmed through scripture, where it states that 'There is none righteous, no, not one' (Romans 3:10). This revelation is based on God's omniscience as He looked down from heaven to assess the hearts of men (Psalm 14:2). The Apostle Paul in Romans elaborates on this, systematically demonstrating that both Jews and Gentiles are under sin and cannot attain righteousness through their works. God's consistent and faithful record in scripture affirms that His assessment of human nature is the ultimate truth, reinforced by the life and teachings of Jesus Christ, who encapsulates God's standards of righteousness.
