What does the Bible say about sin separating us from God?

Isaiah 59 illustrates that it is indeed sin and iniquity that separate humanity from God. From the very beginning, when Adam sinned, this separation caused spiritual death. The passage emphasizes that God's hand is not shortened that it cannot save, but rather, it is our sins that create the divide. The text teaches that all have sinned and come short of the glory of God, highlighting that it is through our transgressions that we fall short. Therefore, recognizing the severity of sin is paramount for understanding our condition and the need for redemption through Christ.
