Personally, I never got this.
A person is born a sinner & thus deserves to die. This is at the forefront of religion. It is the axis that it spins on, making people dependant on their religion/god for freedom from their cursed condition. Romans 5:12.
But, if you actually think about it - how can a person deserve to die?
We don't individually choose life. It is all down to a serious of chances.
It's like inflicting a punishment on someone for something they never did.
How can grown adults, with the ability to reason & follow logic believe that a person somehow deserves to die an agonising death from cancer at the age of 40? Watch this link & tell me that these children deserved this horriffic illnes because of the sin of a man thousadns of years ago.
