I've been curious about this play for so long and now I can finally be glad that I've read it.
What is to say about Goethe's masterpiece? That it represents the human nature and the endeavors which can impede a soul in it's quest for knowledge and the purpose in life.
All the distractions are metaphorically embedded in Mefistofel(the devil) which devises a plan to conquer Faust's soul for all eternity. In the course of sealing the deal, the Devil offer his services to Faust and says that he can make any wish come true.
The path of wanting and having and then wanting anything else consumes the human nature of Faust, and in the end of his life he realizes that by having what he wanted he only managed to want more still and his desires were never making him truly happy. He couldn't have an relationship with a loved one because he managed to seduce them by using the enchantments set by Mefistofel(he wasn't showing his true self and that's the reason why the persons he loved, first Margareta and then Elena, felt that the love brought them great sorrow and chose to end their life).
In a final act of his life he commands a couple of old people, which symbolize the harmony in a married life, to move from their old house into another place, and because they refuse they are murdered and then their house set on fire by soldiers who got the order from Faust. Knowing the result that his command had brought he is sorrowful and realizes that al his life he hasn't gained anything from his companionship with Mefistofel, that he has only impoverished his soul and being of an old age he dies. His soul escapes the grasp of the devil and in the end he regains his place in the heavens alongside the angels and his first love.
