Love in its truest form, Christianity, is what fixes the plagues and problems of the earth. Whether it is abortion, mass murders, greed, etc., love would fix all of it. Without "religion", the earth would be an even bigger mess.
God did not create plagues. God did use plagues in the Old Testament to demonstrate to His people who God is, and to this day we still remember these historical times that are 100% true and real.
There is another power btw (in case you didn't know), the devil.
Hang on, you state that Christianity is "Love" and that religion will fix all problems. Then please explain how the Crusades in the years 1095 to 1291 does not fall under the banner of Religious Mass murder? The crusades show me that religion is the cause of mass murder.
You contradict yourself by saying God didn't create plagues but then say he did.
How do you know your bible is true and correct? The Bible has changed numerous times already through history. It is no longer a work of truth but a work of fiction.
The Devil is no more real than your God.
