Revised Common Lectionary (Complementary)

⁸ Dearly beloveds, be not ignorant of this one thing: that one day is with the Lord as a thousand years, and a thousand years as one day. ⁹ The Lord is not slack to fulfil his promise, as some count slackness, but is patient toward us, and would have no one lost, but would receive all to repentance. ¹⁰ Nevertheless, the day of the Lord will come as a thief in the night, in which day the heavens shall perish with terrible noise, and the elements shall melt with heat, and the earth with the works that are in it shall burn.

¹¹ If all these things will perish, what manner of persons ought you to be in holy living and godliness, ¹² looking for and hasting unto the coming of the day of God, in which the heavens shall perish with fire and the elements shall be consumed with heat? ¹³ Nevertheless, we look for a new heaven and a new earth according to his promise, wherein righteousness dwells.
