Because in order to enjoy eternal life, we must all die; And it doesn't really matter when or how we die. The only thing that really matters is are we ready to die? If the person who is about to die is determined to have faith in the Almighty God, it does not matter whether it is disease, nuclear explosion, nerve gas, or a bullet that will cut the thin rope that keeps the soul taut to the ground. No one is compelled to fear or be anxious about contemplating persecution or death, provided that he has done everything in his power to promote the establishment of the rule of God while he is on the face of this earth.
