Is this the BIBLICAL concept of "Jihad" as commanded by GOD in the Old Testament ?

I've also told these people that their bible was written by taliban like bronze age Palestinians. I've pointed out many of these things to them myself. They don't believe it. They don't know where their religion comes from, they just know what thier pastor tells them. They don't care that Matthew is not written by Matthew, and that the beloved disciple was actually Mary, not John. They just want their belief to be accepted as true. I wish there was a Hell, because if there was, then when these people died they'd learn how wrong they are about their religion and would have to answer to the god they think they're worshiping about why they didn't listen when the atheists told them the truth.
