You mean like to just "have" or like being in a fight? If Jesus was with you in a fight and wasn't being all silly with" turn the other cheek," he could smote (smite?) your enemy with his psychic powers. However, owning a diamond sword and then selling it could make you very wealthy and you could hire mercs to defend you or heck, think of all the good works you could do with the money. Or I suppose if you were really strong, you could swing Jesus around like a big meat hammer and beat up your enemies with him. OR, Jesus I'm sure could be a really good juggler and he could dazzle your enemy and you could like sneak away and escape ! OR, what if you had Jesus AND the diamond sword too! You could get JESUS to wield the sword and you could just stand back and watch. Well, now that I think about it, Jesus might not have the killer instinct that a sword fighter needs. He might just wound them and then forgive them. OK, I'm out of material-- a silly answer for a silly question you troll!
