The second list, found in Galatians 5:19 - 21, again states that those who do practice the following will NOT be in God's kingdom - fornication, idolatry, sorcery, outbursts of wrath, those who spread dissensions and heresies, those who have selfish ambitions, those who are contentious, and still others.
Ultimately, the Bible teaches that ANY sin, unrepented of, brings the death penalty. We might grade sin but God does not. ANY sin is deadly! The Bible defines sin as the transgression of ANY of the laws of God, which includes the ten commandments (1John 2:3 - 4, 3:4).
All mankind, from the greatest to the least, sins (Galatians 3:22). And the penalty for sinning is DEATH (Romans 6:23). Thankfully, God has provided a way to be forgiven - through the unselfish sacrifice of Christ (Romans 5:8).
God does not stop at only forgiving us. He promises there will come a time when He will decide NOT to remember them FOREVER!
"No more shall every man teach his neighbor, and every man his brother, saying, 'Know the Lord,' for they ALL shall know Me, from the least of them to the greatest of them, says the Lord. For I will forgive their iniquity, AND THEIR SIN I WILL REMEMBER NO MORE.” (Jeremiah 31:34)
Thank you for your question regarding the seven deadly sins.
