How do we know we are all sinners?

The doctrine of original sin reveals that all of humanity is inherently sinful due to the fall of Adam. Romans 3:23 states, 'For all have sinned and fall short of the glory of God.' This includes even the most prominent figures in Scripture. In Samson's narrative, we see a man used by God who nonetheless struggles with serious moral failures. The inclusion of such characters emphasizes the universality of sin and the necessity of grace for all people, making clear that no one can claim righteousness apart from God's intervention. As believers, we acknowledge our sinful nature and look to Christ for redemption.
