Second reading: 2 Peter 3:8-14

There is one thing, my friends, that you must never forget: that with the Lord, ‘a day’ can mean a thousand years, and a thousand years is like a day. The Lord is not being slow to carry out his promises, as anybody else might be called slow; but he is being patient with you all, wanting nobody to be lost and everybody to be brought to change his ways. The Day of the Lord will come like a thief, and then with a roar the sky will vanish, the elements will catch fire and fall apart, the earth and all that it contains will be burnt up.

Since everything is coming to an end like this, you should be living holy and saintly lives while you wait and long for the Day of God to come, when the sky will dissolve in flames and the elements melt in the heat. What we are waiting for is what he promised: the new heavens and new earth, the place where righteousness will be at home. So then, my friends, while you are waiting, do your best to live lives without spot or stain so that he will find you at peace.
