Oh I love Gilgalad and all the Elves as well,and they are all good and holy ,the best of what we are when we are the best kind of persons that are in the world. Theyre good role models.They usually go through a test of about fifty years from the tyime their born to see how they will permamently be in personality and choice. They become permamently good by the time their fifty years old if they chosen to be good and love God by then. Then they will be always naturally good and they are immortal,except for grief or a battle wound as Gilgalad had. But then,they can go as spirit to Mando Halls in Valinor,and can ask for a new body. bad elves ,if there were any,would not be immortal after their fifitieth year,they would die that year ,all bad elves do,but thankfully there are not many of those. Badness in elves is a form of inner grief that causes them to pass away by fifty. Elves who chose good and God by fifty are permamnently good and will be immortal. Thankfully,someday good people of God will be resurrected and transformed at the Rapture to immortal life.I believe the Ressurrection day is soon. The Holy spirit would be on the good Elves and He also is upon us good people too.He makes us good and gives us strength.Always pray to Holy spirit in Jesus name and ask for making us good and guiding us to make right decisions and directions. He always helps us.
