How do we know that total hereditary sin-depravity is true?

The doctrine of total hereditary sin-depravity asserts that every human being inherits a sinful nature due to Adam's transgression. Scripture, particularly Romans 5:12, illustrates how sin entered the world through one man, causing death to spread to all because all have sinned. This foundational biblical truth reinforces the necessity for divine intervention through Christ, as all are in desperate need of redemption and grace. Without recognizing our inherited sinfulness, we cannot fully understand our need for the Savior and the reality of our condition apart from Him.
