Quran 4:74: How To Interpret Context?
Injunctions are generalised for the cause they are initiated for can be general cause the nature of the injunction which could be generalised. That if there comes a need to protect religion (the way of Allah), for example a power fight Muslims to disband Islam or persecute people for their faith, the Muslims are supposed to fight it. To fight needs justified cause and these are two: to raise the word of God and to fight against persecution. The prerequisite of jihad is organised effort under a government. When cause and prerequisites are fulfilled it becomes duty of the Muslims to do jihad.
