Fanatics

Want to guarantee that people will die for your cause? Create a system of works salvation and then give people assurance that they'll bypass a life of slavery to legalism by their death for the cause. The knights of the crusades where told they would skip purgatory if they died in holy war, and the suicide bombers of the jihad are told of rich rewards in the afterlife for their martyrdom.

It works. Heck, if I believed I had anything to do with my salvation and someone convinced me that my death for god would allow me instant access to heaven I'd blow myself up too. The idea of having to work for salvation IS that hopeless.

There is therefore now no condemnation for those who are in Christ Jesus. For the law of the Spirit of life has set you free in Christ Jesus from the law of sin and death. For God has done what the law, weakened by the flesh, could not do. By sending his own Son in the likeness of sinful flesh and for sin, he condemned sin in the flesh, in order that the righteous requirement of the law might be fulfilled in us, who walk not according to the flesh but according to the Spirit. (Romans 8:1-4 ESV)
