How do we know that all men are wicked without God's grace?

The assertion that all men are wicked apart from God's grace stems from a thorough examination of Scripture, particularly when considering humanity’s natural disposition. The preacher emphasizes that all men will reveal their propensity for wickedness when the restraints of God are removed. This aligns with biblical passages indicating that 'all have sinned and fall short of the glory of God' (Romans 3:23). The existence of societal ills is not merely a phase of human prosperity lost but a testament to the inherent depravity within mankind. Without God's intervention, individuals exhibit their true nature—a rebelling against Him, thus validating the need for divine grace and the redemptive work of Christ.
