The most gruesome and disturbing photos I’ve ever seen. Heartbreakingly sad in the name of hatred. This is not what God does..this is what man does. Obviously. But this is what some claim God will do to the ‘wicked’ in the last days. (Slaughter them all with the sword). Stare at the images of real men...is that our god?
As stated elsewhere, the prophecies are what God will do in response, because they are going to try and exterminate the Jews and Christians off the planet, and if those days are not shortened NO FLESH WILL BE SAVED. The Day of God's wrath is not going to be the Lord getting together with the world so they can all have a nice little tea party together, Victory.
And in answer to your question, the Lord will not be nearly so barbaric, and you should be careful about accusing Him of being so IMO. The scripture says that He will destroy them with the sound of His voice, not by beheading. Again you are making accusations against the Lord Himself, which I would warn you is not the smartest thing to do. The practice of beheading has always been Satan's method of choice for killing his enemies. It is how he had most of the apostles murdered during New Testament times, because it is symbolic of his desire to separate the body from the head, i.e. Christians from the Lord Jesus Christ their Head. But this is something he will never succeed at.
