When Romans 10:10 speaks about confessing Jesus as Lord, it speaks about confessing that it is Jesus that is Lord, i.e. Jesus is God. 1 Cor 12:3 also says that nobody can say that Jesus is Lord except by the Holy Spirit. Confessing Jesus as Lord has to do with believing, not doing.
Wakati Warumi 10:10 ina ongea juu ya kukiri Yesu kama Bwana, ina sema kuhusu kukiri ya kwamba Yesu ndiye Bwana,yaani Yesu ni Mungu. 1 Wakorintho 12:3 inasema ya kwamba hakuna anaye sema Yesu ni Bwana ila kwa Roho Mtakatifu. Kumkiri Yesu kama Bwana inahusu kuamini, na sio kutenda.
