The difference the Holy Spirit can make is demonstrated in the life of Peter, who, before being filled with the Holy Spirit, denied Jesus three times—and this after he had said he would follow Christ to the death.
Tofauti ambayo Roho Mtakatifu anaweza kuifanya maishani mwa mtu ni kama ile ya Petro, kabla hajajazwa Roho Mtakatifu alimkana Yesu mara tatu, na alikuwa mbeleni ameahidi kumfuata Yesu mpaka kwenye hatari ya kifo angekufa naye.
