How do we know the necessity of salvation is true?

The necessity of salvation stems from the foundational truth that all have sinned and fall short of the glory of God (Romans 3:23). The fall of Adam represents the moment where sin entered the world, and it works itself out in the lives of all humanity, highlighting our total depravity. Without recognizing our dire situation, we fail to understand our need for salvation. God's justice necessitates a payment for sin, which reveals the importance of Christ's redemptive work as our substitute. Hence, the revelation of our sinful state is crucial, as only by acknowledging it can we truly recognize the necessity of salvation provided through Jesus Christ, the only means by which we can be restored to fellowship with God.
