If it does not, then we really cannot be sure of anything (spiritual or not), and we end up either an agnostic, unsure if we can really know anything, or a pluralist, accepting every position because we are not sure which, if any, is right.
Kama haimo, basi sisi kweli hatuwezi kuwa na uhakika wa kitu chochote (y kiroho au isiyo ya kiroho), na sisi huishia kuwa agnostiki, bila uhakika kama tunaweza kweli kujua kitu chochote, au kwa wingi, kukubali kila nafasi kwa sababu hatuna uhakika kwamba kama lolote, ni la haki.
