2 Peter 3:13-15

But in accordance with His promise we expectantly await new heavens and a new earth, in which righteousness dwells. [Is 65:17; 66:22] So, beloved, since you are looking forward to these things, be diligent and make every effort to be found by Him [at His return] spotless and blameless, in peace [that is, inwardly calm with a sense of spiritual well-being and confidence, having lived a life of obedience to Him]. And consider the patience of our Lord [His delay in judging and avenging wrongs] as salvation [that is, allowing time for more to be saved]; just as our beloved brother Paul also wrote to you according to the wisdom given to him [by God]
