Commentaries:
Paul is giving us a command here, an imperative, but it actually goes further. In I Corinthians 16:13, there are four imperatives in this one verse, which is itself just six words in the original Greek: 1) watch, 2) stand fast in the faith, 3) be men (courageous), and 4) be strong.
The word watch means "to keep awake, be vigilant, be watchful." For us, that means keeping an eye on the world around us, and more importantly, paying attention to our spiritual condition. To stand fast in the faith means "to be stationary (anchored), to persevere, to be convicted of our beliefs." As we saw, to be men is "to be courageous," but not so much in a physical sense as in the convictions of our spiritual life. Finally, to be strong implies "to increase in vigor, to be strengthened, to increase in faith."
These four imperatives can be viewed in military terms, and Paul uses such terms quite often in his epistles. Living in the days of Roman rule, he commonly saw Roman legions in his travels. His audience, also living within the Empire, was quite familiar with soldiers and their duties.
We can imagine a sentry on guard duty, at attention, peering into the night, listening intently for any unusual noise. He has to fight off sleep lest the enemy sneak up on him and kill him, opening the camp to attack. We can realize how this applies to Christian life.
The other imperatives--standing fast in the faith, being strong, and living like men--are also better understood as military imagery. Many are familiar with the story of the Battle of Thermopylae in 480 BC, when Sparta’s King Leonidas and his 300 Spartans, along with 700 Thespians, 400 Thebans, and perhaps a few hundred others, fought to the death against the million-man army of Persian Emperor Xerxes. King Leonidas and his men knew that they would die; they knew the odds were overwhelmingly against them. But they felt compelled to try to stop the enemy and save their country.
Certainly, this encapsulates these four imperatives!
As stunning as that example is, we should bring it down to a more personal level: to an army of one. Outnumbered as they were, the Spartans and their allies still had other warriors fighting with them on either side, at least until the very end. What if we were absolutely by ourselves?

Courage and the Dog Soldier
Maintaining good physical health is a stewardship responsibility that comes with our calling. We owe this obligation to our Creator God just as surely as we have spiritual responsibilities toward Him. We may deem these physical responsibilities as less important, but that does not nullify them.
Paul uses "body" in a dual sense, as both the spiritual bodythe churchand the physical body of each member. Sin works to destroy both, and God did not create us to sin.
The sin here is fornication, porneia, which includes a broad range of sexual sins that pervert the right, godly use of sex. Paul uses it to illustrate sin's destructiveness. Sin is somewhat like junk food: It may "taste" good to the senses for a while, but before it is through, it will come back and harm us with its destructive properties. Junk food may taste good going down, but all the while, it is depriving the body of life-giving nutrients it needs to be truly strong.
In Genesis 1:28, God gave mankind dominion and responsibility to rule over His creation. Our own lives and bodies are the closest and most specific areas of God's creation over which we are to rule. In Genesis 2:15, God commands us to dress and keep His creation, giving us more specific direction in this obligation. To dress and keep means we are to beautify, enhance, embellish, and improve the raw product, along with maintaining it and inhibiting its decay and degeneration. In Genesis 4:7, God admonishes Cainand us in principlethat a desire to go contrary to God's desires will always be part of this mix. Sin lies at the door, He warns, but we must master it. In essence, we must stir up the spirit in us to discipline ourselves. In combining these major principles, we can see that God means our major areas of operation in His purpose are those closest to us.
