How do we know that we are all sinners before God?

The reality of our sinfulness is established through Scripture, particularly in Romans 3:23, which states that all have sinned and fall short of the glory of God. This universal condition is reflected in the experience of the woman in Mark 5 who suffered for twelve years, pointing to our spiritual condition—guilty and helpless under the weight of God's law. God's law reveals our sin, and it is through our understanding of the law that we recognize our desperate state. Consequently, it underscores the necessity of turning to Christ for redemption, as true salvation is found only in Him.
