Charles Spurgeon Commentary 1 Thessalonians 5:6-7

"so then let us not sleep, as do the rest, but let us watch and be sober. For they that sleep sleep in the night: and they that are drunken are drunken in the night." — 1 Thessalonians 5:6-7 (ASV)

But let us watch and be sober. For they that sleep sleep in the night; and they that be drunken are drunken in the night.

Even in Paul's day, drunkenness was a thing that seemed more at home in darkness than in the light. As for us, brothers, let us never be carried away by excess – either drunkenness of body or inebriation of mind – for there is a drunkenness which renounces the cup, and yet is as flagrant an intoxication as the other is. We may be drunk with pride, or drunk with ambition, or drunk with wrath, or drunk with worldliness; but we are to avoid all these evils, because we are not now in the night, when these drunken fits might be in some sort of harmony with the surrounding darkness.
