1 Thessalonians 5:4-6

Amplified Bible, Classic Edition

⁴ But you are not in [given up to the power of] darkness, brethren, for that day to overtake you by surprise like a thief.

⁵ For you are all sons of light and sons of the day; we do not belong either to the night or to darkness.

⁶ Accordingly then, let us not sleep, as the rest do, but let us keep wide awake (alert, watchful, cautious, and on our guard) and let us be sober (calm, collected, and circumspect).
