Watchmen and Warriors
There’s another word picture used in this passage—that of a watchman. The Scripture says, “Unless the LORD watches over the city, the watchman stays awake in vain” (v. 1).
We have here a picture of a sentinel or guard, someone who’s been assigned and has accepted the responsibility of standing guard over a city. He can’t go to sleep on his shift; he’s got to stay alert and awake. He needs discernment to recognize when an enemy is coming.
We have been given the assignment of being protectors, looking out over the city that God has entrusted to us.
The third picture in this passage is of a warrior: “Like arrows in the hand of a warrior are the children of one’s youth” (v. 4). The picture here is of a battlefield, and our sons and daughters are ammunition. They are arrows in battle, and God intends that we release and send them out into the culture.
Those arrows have to be prepared—carefully shaped and formed. They have to be shot in the right direction, toward the appropriate target. Our effectiveness as warriors, in many senses, determines the effectiveness of those arrows. If they’re not shaped correctly, or if they’re sent in the wrong direction, they’re not going to fulfill their purpose.

The psalmist tells us that there’s a house to be built, a city to be guarded, and a battle to be fought. If the workman cuts corners, if the watchman falls asleep or gets distracted while he’s on his shift, or if the warrior fails to show up for battle, we’re going to have problems. Lives can actually be endangered. These are strategic, vital roles.
When you think about your family, it’s not just a matter of “Will my kids make it?” or “Will we have a good family?” or “Will we have an intact home?” There’s a much bigger picture here.
