This guy is confused.
War, at times, is necessary, because of the evil nature of men.
I wouldn't be so quick to write off what he's saying there. I don't think a newspaper article is going to give you the full context of what he says. It's probably a "sound-bite" that the reporter grabbed a hold of, which was part of a lot more that he had to say about it. That's how it goes sometimes, with reporters.
Of course, I don't know either what was the full context in which that comment was a smaller part. And if I don't then neither do you.
But, I can guess how it fits into the broader picture of the Gospel of Salvation. Forgiveness is the issue here, and although we currently live in a sinful world -- there is coming a time in which we will still live in a sinful world -- but -- there will be no more war in the world.
That's during the 1,000 year Kingdom of Christ in the world. During this time, there will be no more war, but there is still a sinful world that sinful people live in -- during that time when the Messiah of Israel is ruling and reigning over all the nations of the world.
And so, I would put that comment in the framework of the forgiveness of the cross, of the Gospel of Salvation (according to the Scriptures) that God offers us all. I would put that comment in terms of that statement in the Bible of forgiving 70 times 7, and about how unless one forgives, then the Father in Heaven won't forgive that person.
Yes, I would say that forgiveness is at the core of the context of the Gospel of Salvation that Jesus, the Messiah of Israel brings to the world and to each individual.
In short, don't take a news report as "gospel."
