Why do I need to be justified?

The need for justification arises from the fundamental truth presented in Romans 3:23, which states that all have sinned and come short of the glory of God. This universality of sin means that no one is inherently righteous or deserving of God's acceptance. Before a holy God, our sins create a separation, as noted in Isaiah 59:2, showing that we cannot achieve righteousness on our own. Each individual's sinfulness and rejection of God's law lead to the necessity for a just solution—justification through Christ, who alone can reconcile us to God and meet the requirements of His law.
