The Saint John Theologos advise us

Don't love the world, or everything that belongs to the world. If someone loves the world it means that he has not into him the love for the Father. For everything that belong to the world. - the inappropriate desires, the wish to gain everything that our eyes see and our false view that we have human belongings - they are not flow from the Father but from the world who lives into the sins.  The world, however, goes and sometimes it extincts, and with it all those that people desire to possess within it. But who does obey the rules of the God will live forever...
