For lurkers, I repeat it here along with the other verses that comprise the thought:
And account [that] the longsuffering of our Lord [is] salvation; even as our beloved brother Paul also according to the wisdom given unto him hath written unto you; As also in all [his] epistles, speaking in them of these things; in which are some things hard to be understood, which they that are unlearned and unstable wrest, as [they do] also the other scriptures, unto their own destruction.
Ye therefore, beloved, seeing ye know [these things] before, beware lest ye also, being led away with the error of the wicked, fall from your own stedfastness. But grow in grace, and [in] the knowledge of our Lord and Saviour Jesus Christ. To him [be] glory both now and for ever. Amen. - 2 Peter 3:15-18
