⁴ But you, our Christian friends, know about these things. You are not like people who live in the dark. So when the great day of the Lord happens, it should not suddenly surprise you, like a robber might surprise you. ⁵ All of you are people who belong to the light and to the day. We who are believers do not belong to the night or to the dark. ⁶ So we must watch carefully. We should be like people who stay awake. We should not be like other people who are sleeping.
