Well, because it’s contrary to what’s revealed to us by God in His Word, the Bible.
Pope Francis, believed by the Catholic Church to be a direct successor of the apostle Peter, spoke about the current war in Ukraine:
More than a month has passed since the invasion of Ukraine, since the start of this cruel and senseless war, which, like every war, is a defeat for all, for all of us…
We must repudiate [refuse to accept] war, a place of death where fathers and mothers bury their children, where men kill their brothers without even seeing them, where the powerful decide and the poor die. War does not only devastate the present but also the future of society…
Faced with the danger of self-destruction, humanity must understand that the time has come to abolish war. To erase it from human history before it erases man from history…
Enough. Stop. Let the weapons fall silent. Negotiate seriously for peace…
War cannot be something that is inevitable. We cannot get used to war.Pope Francis calls for abolishment of war “before it erases man from history”, CNN’s Sharon Braithwaite in London, March 27, 2022
These are lovely sentiments but appear to have sidelined, or forgotten, the key issue: our addiction to sin.
Since humanity’s fall (as illustrated in Genesis 3), we’ve always been at war. Whether relational, national, cultural, or spiritual, we’re addicted to competition, separation and hostility. For example, the United States of America, the “Leader of the Free World“, has enjoyed 15 years of peace since its Independence Day in 1776 (7 to 10 generations ago).
I’m sorry, Francis, but wars are not only inevitable; they define us. Humanity will be at war until the abolition of sin and the new heavens and earth are unveiled.
Let’s have a quick look at our history according to God:
34 ‘Do not suppose that I have come to bring peace to the earth. I did not come to bring peace, but a sword.Matthew 10:34
3 The Lord is a man of war;Exodus 15:3
the Lord is his name.
6 You will hear of wars and rumours of wars, but see to it that you are not alarmed. Such things must happen, but the end is still to come. 7 Nation will rise against nation, and kingdom against kingdom. There will be famines and earthquakes in various places.Matthew 24:6-7
7 When you hear of wars and rumours of wars, do not be alarmed. Such things must happen, but the end is still to come. 8 Nation will rise against nation, and kingdom against kingdom. There will be earthquakes in various places, and famines. These are the beginning of birth-pains.Mark 13:7-8
Okay, Jesus (God) has told us that wars are inevitable. Although “It is finished“, we’ve been involved in spiritual warfare against Satan and his minions since the birth of sin in Genesis 3 and our rebirth through the blood of Christ.
So, what are we to do now? Do we disband the United Nations and other international peace movements and adopt a “come what may” ideology? Or do we fight against those who stand in the way of peace? Vladamir Putin’s “Special Military Operation” to eradicate the Ukrainian people is wholesale evil.
Irrespective of His omniscience, God is weeping.
