(1) Death is universal (Romans 4:12,14), all die: sinless infants, moral people, religious people, equally with the depraved. For a universal effect there must be a universal cause; that cause is a state of universal sin (Romans 5:12).
If we all die becuase of original sin, but Jesus was sacrificed to erase that sin, why do people, at the least Christians, still die? If Jesus wiped it away, its effects should be gone.
