The apostle Peter says the following about those people who talk about things they do not understand, they are irrational beings and always act as if they were believers. However, their actions do not support their faith, so it is inevitable that they will perish in their own doom as their time has run out.
They are like animals, fools and very easy prey for the enemy of our souls. Their minds are blocked and all they think about is leading astray those who do do the divine will of the Lord. They mistakenly think that the day of the Lord will not come to judge the unrighteous for their evil deeds.
