Remember the teaching that you were given and that you heard. Hold firmly to it and turn from your sins. If you don't wake up, I will come when you least expect it, just as a thief does.
The day of the Lord's return will surprise us like a thief. The heavens will disappear with a loud noise, and the heat will melt the whole universe. Then the earth and everything on it will be seen for what they are.
Remember that Christ says, "When I come, it will surprise you like a thief! But God will bless you, if you are awake and ready. Then you won't have to walk around naked and be ashamed."
Think about where you have fallen from, and then turn back and do as you did at first. If you don't turn back, I will come and take away your lampstand.
