Well, those who have faith should fear no death. Quoting: Lada D
However, the Lord is not adverse to the easing of suffering.
We all have bigger things to worry about in our lives, and Christ knows our struggles with confusion in certain matters.
We are all made up of energy! God knows this already, it was we who didn't know this till recently in world history. Energy does not die. If energy is removed from something it goes somewhere else but it does not disappear or die!
Einsteins theory of relativity in how mass is energy and does not die but is simply transformed into new energy is the best example I would have to offer.
Einstein demonstrated that E=mc^2, that energy equals mass x the speed of light squared. What this equation relates simply is that energy and matter are one and the same thing. Matter is just a much more condensed and "slower" form of energy. Note, that everything in the universe vibrates, including the atoms of molecules of matter (mass). So nothing is completely "at rest" ever. Energy may be transformed but it may not be destroyed. This is the law of the conservation of energy. Exploding a nuclear weapon demonstrates that Einstein was right - matter can be converted to it's equivalent energy, and given the right conditions (most likely, a tremendous source of gravity, such as a black hole), energy can be condensed into matter.
"For the believer, both the evidence of science and the failure of science to explain the paranormal is all the proof they need. For the skeptic, no evidence no matter how scientific will ever be proof enough." ~John Zaffis
God tells you what is to happen to your energy once it is done here. The reason God all throughout the bible tells you to not fear death is because he knows of other things outside of your knowledge that you may never know.
