In the New King James Bible 2 Peter 3:7 reads, "But the heavens and the earth which are now preserved by the same word, are reserved for fire until the day of judgment and perdition of ungodly men.." In the KJV it reads, "But the heavens and the earth, which are now, by the same word are kept in store, reserved unto fire against the day of judgment and perdition of ungodly men." Note the difference -- in the NKJV, the word of God preserves the heavens and the earth, while in the KJV, by the word of God they are kept for the destruction of the last days.
