What does the Bible say about the fatal flaw of sin?

The Bible describes the fatal flaw of sin rooted in our nature as being dead in trespasses and sins, as mentioned in Genesis 2:17, highlighting the spiritual death that Adam experienced upon disobedience. This flaw, which is inherited from Adam, leaves humanity at enmity with God and unable to comprehend divine truth without regeneration. Romans 5:12 affirms that through one man sin entered the world, and because of this, all are condemned. The good news is that through Christ, this separation caused by sin can be repaired, as believers are reconciled with God through His grace.
