Whoever believes in the Son has eternal life; whoever does not obey the Son shall not see life, but the wrath of God remains on him.
John 3:36
Among these we all once lived in the passions of our flesh, following the desires of body and mind, and so we were by nature children of wrath, like the rest of mankind. But God, being rich in mercy, because of the great love with which he loved us, even when we were dead in our trespasses, made us alive together with Christ—by grace you have been saved—
Ephesians 2:3-5
This is evidence of the righteous judgment of God, that you may be considered worthy of the kingdom of God, for which you are also suffering— since indeed God considers it just to repay with affliction those who afflict you, and to grant relief to you who are afflicted as well as to us, when the Lord Jesus is revealed from heaven with his mighty angels in flaming fire, inflicting vengeance on those who do not know God and on those who do not obey the gospel of our Lord Jesus.
2 Thessalonians 1:5-8
