What does the Bible say about being a sinful man?

In Luke 5:8, when Peter realizes the divine power of Jesus in performing a miraculous catch of fish, he responds by acknowledging his sinfulness. This moment of conviction reflects a profound understanding of human unworthiness before a holy God. Throughout Scripture, we see that all have sinned and fall short of the glory of God (Romans 3:23), and recognizing our sinful nature is vital for true repentance and faith. It is through this awareness that one may come to appreciate the depth of God's grace and mercy, which is underscored by the death and resurrection of Christ.
