"In the days to come, the mountain of the Lord's house shall be established as the highest mountain and raised above the hills," writes the prophet Isaiah.
"Many peoples shall come and say: Come, let us go up to the Lord's mountain ... that He may instruct us in His ways, and we may walk in His paths. ...
"They shall beat their swords into plowshares and their spears into pruning hooks; one nation shall not raise the sword against another, nor shall they train for war again."
This prophesy will certainly be fulfilled when Christ comes again and His kingdom is totally established. There's no stopping it. But it could happen even before then. If only we would go up to the Lord's mountain and allow Him to instruct us in His ways, and wholeheartedly walk in His paths.
But instead it seems like so much of the world, and so many people in power, are committed to going down into the dark valley of violence and war, ignoring the Prince of Peace's way.
The U.S. Congress will probably grant President Obama's request to use expanded military force - including boots on the ground - to fight the self-proclaimed Islamic State.
In his request known as the "Authorization for Use of Military Force," Obama is asking Congress to approve the deployment of U.S. troops to Iraq for "enduring offensive ground combat operations" for at least three years.
Didn't the nearly nine years of war in Iraq teach us anything?
Military action against the Islamic State is playing into their hands. They want to draw the U.S. into a ground war, so they can trumpet the message that "Christian crusaders" have launched an invasion upon Islam. Such a scenario would flood their ranks with radical Islamists from around the world.
After the start of the first Gulf War in 1991, St. John Paul wrote, "No, never again war, which destroys the lives of innocent people, teaches how to kill, throws into upheaval even the lives of those who do the killing and leaves behind a trail of resentment and hatred, thus making it all the more difficult to find a just solution of the very problems which provoked the war."
It can be strongly argued that the devastation caused by the U.S.-led invasion and occupation of Iraq largely set the stage for the birth of the Islamic State and several other Jihadist groups.
Instead of fueling more war and terrorism, we need to pressure our government to provide far more humanitarian assistance to our fellow Christians, and all others who are suffering from the barbarism of the Islamic State.
Also, we need to kindly consider making a generous donation to Catholic Relief Service's emergency fund for the Middle East.
In his famous 1967 "Beyond Vietnam" speech, the Rev. Martin Luther King said, "Our greatest defense against communism is to take offensive action in behalf of justice. We must with positive action seek to remove those conditions of poverty, insecurity and injustice which are the fertile soil in which the seed of communism grows and develops."
And the same is true with terrorism today. If we will muster up the faith and courage to redirect the vast resources dedicated to war, and instead put them at the service of removing "those conditions of poverty, insecurity and injustice which are fertile soil" in which the seed of terrorism grows and develops, we will have then finally beat our swords into plowshares.
