Naruto has the power!!!
UCHIHA (1st son) SENJU(2nd,and the gifted to bring peace to world)
UCHIHA UZUMAKI SENJU
the sage of the six paths had two sons , the uchiha's ancector,he wa born with sages ''eyes'':that had powerful chakra and spiritual energy ,and the sanjus ancector,that had sages body:pshysical power and energy......when the sage was in the deathbed and asked them how the each ,if the sage gave him power,will bring peace to the shinobi world ...the uchiha said by power and the senju said by the good will power and love,pure feelings,and so the sage gave the ''power'' to accomplish his dream,to bring peace,to senjus ancector and not to uchiha....but uchihas hated them for this reason so hey battled,and so senjus hated them too....but senjus was the main family,in japanese as we know,but uzumakis who was related with them bloodly were they the ''non''-main family,cause they were both uzumaikis and senjus ,senjus ancector kids ..if yes heres my theory.... in the moment that SOTSP selected senju for his love to bring peace,and the love vanished and switched with hate for uchihas so the will went to the uzumakis,and not to the main family to senjus....so naruto cause they are related by blood with senjus,related by blood with the SOTSP and the chosen one,the one with the love in his heart and the wiil power was nly able to bring the peace by the power that the SOTSP gave...naruto has that willpower and love,as said to the pain ,that this can bring peace,so maybe he has the power of the SOTSP..and thats why he was able to use that sealing tech......wanna to hear ya...and tell me to explain it again ,if u wanna it more clear!!!!!
