Rules of Engagement
Some of India's best troops are stationed on the border with Pakistan. They are the best not because they are good at sneaking or sniping. They are the best because they have self-control and know the consequences of creating or responding to a provocation. At the border, there are bigger issues than personal protection, ego or vengence.
In the military, before a soldier is sent to his station, he and his entire unit are instructed on the rules of engagement... when you may and may not shoot. The airports I travel through are often protected by sand bagged security checkpoints. Simple rules of engagement might be something like, "Do shoot someone approaching with an obvious gun or bomb; do not shoot the passengers."
The rules help troops evaluate when the threat is real and how they are to respond. Rules of engagement are important because the over reaction of a soldier is as great a danger as the attack of an enemy. Over reaction enflames a situation and endangers more lives. It can turn a simple exchange into a full scale war.
Jesus clearly had rules of engagement. "When they insulted him he did not retaliate. When he suffered he made no threats. Instead he trusted himself to Him who judges justly." (I Peter 2:23).
For a Christian, the rules of engagement would be something like this: When someone offends you, you are not authorized to shoot back. If they hit you on the right cheek, turn the left cheek. If they take your silverware, give them the silver candlesticks as well (Les Miserables). Always be aware of the consequences of creating or responding to a provocation. In the kingdom, there are more important issues than ego.
