Revenge

"...in flaming fire taking vengeance on those who do not know God, and on those who do not obey the gospel of our Lord Jesus Christ." 2 Thessalonians 1.8

The Divine revenge is not just against those who do not know the Lord God, but also against those who are disobedient to the Gospel of the Lord Jesus. That is, those who have occupied a church pew every week, listen and learn the teachings of Jesus and yet, still do not practice them. What good is it to have faith in Jesus but not obey His Word? Would such faith be able to save him?

HEAR

"Thus says the Lord God:’ He who hears, let him hear; and he who refuses, let him refuse; for they are a rebellious house'."         Ezekiel 3.27

The Holy Bible can be summed up in two words: listen and obey. Those who have spiritual ears listen and obey. Not only do they listen, but they also obey.
Those who disobey are rebellious just like Lucifer was and will suffer the consequences of their rebelliousness.
