How do we know the need for a Savior is true?

The recognition of our need for a Savior stems from the biblical doctrine of original sin and the comprehensive understanding of the nature of sin. Scriptures such as Romans 3:23 affirm that all have sinned and fall short of the glory of God, illustrating our universal need for redemption. The preaching of God's law reveals our inability to achieve righteousness on our own, making the case for the necessity of a Savior compelling, as stated in Galatians 3:24, where the law acts as our tutor to bring us to Christ. Christ's substitutionary death is the essential answer to humanity's plight, providing the righteousness and forgiveness we cannot achieve by ourselves.
