"Therefore let us not sleep, as do others; but let us watch and be sober." 1 Thessalonians 5:6
Here sobriety is opposed to sleepiness, and is connected with walking in the light and in the day, as sleepiness and its frequent cause, drunkenness, are connected with darkness and night.
One of the greatest curses God can send on a people and its rulers, its prophets and seers, is a spirit of deep sleep, as the prophet speaks: "For the Lord hath poured out upon you the spirit of deep sleep, and hath closed your eyes; the prophets and your rulers, the seers hath he covered." But to be sober is to be awaked out of this sleep, and, as a consequence, to walk not only wakefully but watchfully. It implies, therefore, that careful, circumspect walking, that daily living, moving, speaking, and acting in the fear of God, whereby alone we can be kept from the snares spread for our feet at every step of the way.
How many have fallen into outward evil and open disgrace from want of walking watchfully and circumspectly, and taking heed to their steps. Instead of watching the first movements of sin and against, as the Lord speaks, "the entering into temptation," they rather dally with it until they are drawn away and enticed of their own lust which, as unchecked, goes on to conceive and bring forth sin, which, when it is finished or carried out and accomplished in positive action, bringeth forth death.
