So, are you saying that God is the beast?First you answer me. If killing is a sin then how is God Himself not a sinner? If killing is a sin then how can Jesus Christ escape such a sin because He will destroy many? You are tap dancing if you cannot answer that very question. God doesn't sin and yet God kills. So is there "killing" which isn't a sin?
As to who are you to tell me... not much in all honesty. Your doctrine is wrong.
The truth of the matter is that God uses satan as a tool to bring about correction..through governments of men...and, He has established those governing powers, but He in NO way is responsible for the evil that they ALL sow...He cannot even be tempted with evil.
Wars are the result of lust, according to the bible.
Some will say that there is such a thing as a "just" war, and I would agree to that, but, the difference is that God does not do the warfare HIMself, HE sends carnal nations to fulfill that task...whom are led of the flesh, and follow satan right into the pits of it all.
The new covenant DEMANDS and COMMANDS we beat our swords into plowshares...have you read that verse? We, as christians are supposed to be lights in a dark world...showing forth the way of love...not hiding our candles under a basket of worldly ways.
