2 Peter 3:11-12

Since all these things are to be destroyed in this way, what kind of people ought you to be [in the meantime] in holy behavior [that is, in a pattern of daily life that sets you apart as a believer] and in godliness [displaying profound reverence toward our awesome God], [while you earnestly] look for and await the coming of the day of God. For on this day the heavens will be destroyed by burning, and the [material] elements will melt with intense heat! [Is 34:4]
