Therefore, I intend to constantly remind you people about these things [i.e., those mentioned in verses 5-11], even though you [already] know them, and have been established in the truth you now possess.

For we did not use cleverly conceived stories when we told you about the power and coming of our Lord Jesus Christ, because we were eyewitnesses of His Majesty [i.e., the apostles had personally seen the miraculous power of Jesus].

However, these people are like unreasonable, ignorant creatures of instinct, born as animals which are [to be] caught and destroyed. They speak out against things about which they are ignorant. In [the process of] destroying others, they will certainly be destroyed themselves.

The Lord is not slow about keeping His promise, like some people are, but is [simply] being patient with you, since He does not want anyone to be destroyed, but He wants everyone to repent [i.e., change their hearts and lives].

He spoke about these things in all of his letters, which contain some parts that are difficult to understand. [Because of this], ignorant and unstable people twist [his writings], just as they also do to the other Scriptures, to their own destruction.

Therefore, dearly loved ones, since you know about these things ahead of time, be on your guard so that you are not led astray by the error of lawless people, and [thus] fall from your own stability [i.e., your safe or secure position in Christ].
