The Book of Joshua shows that God ordered believers to kill people of other religions in genocidal warfare.
In the Book of Joshua, God ordered believers to kill even women and children, and that is genocide.
In other words, according to the Holy Bible, genocides are justified when ordered by God.
Why does God order genocide (killing of the entire race) in the Holy Bible?
One possible answer is that God values true religion so much that God wants true religion even if it means killing entire races.
In the United States of America, Americans killed Indians (Native Americans) who were of different religion, in order to advance Christianity in America.
The idea that genocidal killing is justified to advance Christianity in America can be described as “Manifest Destiny”.
Because Americans believe in the Holy Bible, they supported genocidal killing in order to protect and advance true religion in America.
But America is not alone in the use of genocidal war (killing of entire race) in order to protect and advance true religion.
In World War 2, Germans carried out genocides in Germany in order to protect and advance the true religion in support of the Holy Bible.
The Vatican and the Roman Catholic Church supported gencide of Jews in Germany to protect Germany’s Christianity and advance Christianity in Germany because Catholic theologians understood the theological implications of the Book of Joshua.
In Christianity, genocidal killing of people of other religions is always justified in order to protect Christianity and to advance Christianity, and this is the unifying theme of Christianity since the very beginning.
Christianity has never been tolerant of other religions, because Jesus Christ is not tolerant of other religons.
Jesus Christ spent every day attacking Judaism in the capital city of the Jewish nation of Israel, because Jesus Christ does not support religious tolerance.
The New Testament clearly states that Jesus Christ is the only way to salvation. The New Testament is intolerant of other religions.
Christianity has envisioned itself as a spiritual reality in violent war with evil in the world, such as homosexuality, and that all Christians are “Christian soldiers”. This language of warfare is found in the Holy Bible.
Jesus Christ is called “King of kings” and the Book of Revelations clearly show Jesus Christ leading Christians in genocidal killing to advance Christianity on earth.
Throughout history, Christians have died because of the faith that Jesus Christ is the only way to salvation.
For 2,000 of Christianity, Christians have killed in warfare to advance the idea that Jesus Christ is the only way to salvation and all other religions lead to eternal damnation.
True Christians are willing to die to advance True Religion of Christianity.
