How should the Amish respond?

Romans 12:17-18
17 Do not repay anyone evil for evil. Be careful to do what is right in the eyes of everybody.
18 If it is possible, as far as it depends on you, live at peace with everyone.
19 Do not take revenge, my friends, but leave room for God's wrath, for it is written: "It is mine to avenge; I will repay,"says the Lord.
20 On the contrary: "If your enemy is hungry, feed him; if he is thirsty, give him something to drink. In doing this, you will heap burning coals on his head."
21 Do not be overcome by evil, but overcome evil with good.

We are at this present time living in a world of considerable conflict and spiritual or emotional unrest.
Canadian soldiers are facing death each day as they try to fight an enemy who has no fear of death.
Our developed world, led by the US and Britain, is fighting against an enemy that has no borders, that has no organised armies, that has no institutional buildings. It is an enemy that lives in the hearts and minds of its followers. The world is taught to believe this enemy is called "Terrorism," but discerning Christians know that this enemy is the Spirit of the Anti-Christ.
But the Spirit of Anti-Christ is not just "out-there" in lands distance to us, for it also lives among us and will think nothing of taking the lives of innocent helpless Christians, as we have just seen in the shooting deaths of the Amish children in the US this week.
But how will the Amish respond?
Let us pray their response is, in fact, Christian and not the way the world has responded with its bombs and its own atrocities.
Let us pray, as Paul has written in Romans, that they will not be overcome by evil, but will have the faith and courage to overcome evil with good.
