I can’t tell you that I am not a religious person at all. I just know that it has been said to me many times over by my family members.
The New Testament is pretty clear that once you become a Christian you get access to a distinct set of super powers known as "the fruit of the spirit", one of which is Peace.
I don’t know I personally don’t believe in the Bible or any religion and don’t really give it any thoughts. But the rest of my family is very religious
