Do you know what the religious maniacs responsible for so much bloodshed for the last few millennia had in common? They all thought they knew what God "sanctioned" or "approved of". I don't know you and I have no reason not to respect your religious convictions, but just FYI, for secular people-- as well as a lot of religious types, I hear tell-- reading the phrase "God has sanctioned war in the past" is about as frightening as it gets, not to mention that it sounds like a declaration right out of the fourteenth century. I'd be the last to knock anyone for loving God and living by his beliefs, but I get a little leery when said beliefs start taking on an air of infallible certainty. People claim to know the mind of God? Or claim His book is all we need-- a book written by men? Seems like maybe God should be a mystery, maybe to His own followers most of all. But, hey, skepticism should never spoil a party.
"Hello, I'm God, and I approved this carpet bombing."
I find more frightening a denial of God and a rejection of all moral codes. If someone says, like that in some circumstances some amount of warfare is acceptable, always under the watchful eyes of God and with love and kindness considered honorable virtues, it is frankly not at all frightening. What is
very unnerving is when people believe something along the lines of: "“There is no God. When communists deny God, they simultaneously deny every virtue and every value which originates with God. There are no moral absolutes, no right and wrong. The Ten Commandments and the Sermon on the Mount are invalid!” - Karl Marx
To reiterate: believers in God - secularists
Sometimes war is acceptable - no guidlines, either for good or bad, on the subject
God watches everything and will judge everyone - no higher authority, no judgment for bad deeds
An expectation of morality and a code of conduct - doubts the existence of predefined "morality" and no automatic code of conduct
So which seems more threatening, when someone who believes in a higher authority and judgment and ultimate punishment for bad deeds and has a code of morality says that in some situations and circumstances war can be acceptable, or when someone completely denies any higher authority, judgment, or mandatory expectations of love, mercy, etc.
And the Bible was not written by men. It was written by God therefore whatever it says is correct and acceptable. Many secularists such as yourself freely say it's written by men even to Christians and expect them to agree with them, but no, I don't. I trust the Bible, which is not afraid to demand certain characteristics of people and will not excuse evil than men.
