Answer: When we participate in the Divine Nature of God through His very great and precious promises, we escape the corruption in the world caused by evil desires, (verse 4).

Listen to what happens when we accept the Word of God and obey it, escaping the corruption in the world, and then turn our backs on that Word:
2 Peter 2:20-22: "If they have escaped the corruption of the world by knowing our Lord and Savior Jesus Christ and are again entangled in it and overcome, they are worse off at the end than they were at the beginning. It would have been better for them not to have known the Way of righteousness, than to have known it and then to turn their backs on the sacred command that was passed on to them. Of them the proverbs are true: ‘A dog returns to its vomit,' and, ‘A sow that is washed goes back to her wallowing in the mud.'"
Hebrews 10:26-31: "If we deliberately keep on sinning after we have received the knowledge of the Truth, no sacrifice for sins is left, but only a fearful expectation of judgment and of raging fire that will consume the enemies of God. Anyone who rejected the law of Moses died without mercy on the testimony of two or three witnesses. How much more severely do you think a man deserves to be punished who has trampled the Son of God under foot, who has treated as an unholy thing the blood of the covenant that sanctified him, and who has insulted the Spirit of grace? For we know Him Who said, ‘It is Mine to avenge; I will repay,' and again, ‘The Lord will judge His people.' It is a dreadful thing to fall into the hands of the living God."
