It is the same Holy Spirit Jesus was just talking about in John 14-16. You cannot say in John 16:12-13 "spirit" refers to one person, and spirit refers to the Holy Spirit or something else in John 14:16-18,25-26; 15:26; 16:5-11; 16:14-15.
Ni Roho Mtakatifu yuleyule ambaye Yesu alikuwa anamwongelea kwenye Yohana 14-16. Huwezi kusema kuwa kwenye Yoh 16:12-13 "roho" inamaanisha mtu mmoja, na roho inamaanisha Roho Mtakatifu au kitu kingine kwenye Yohana 14:16-18,25-26; 15:26; 16:5-11; 16:14-15.
