Calvinism includes the belief that God’s grace is irresistible, while Arminianism says that an individual can resist the grace of God. Irresistible grace argues that when God calls a person to salvation, that person will inevitably come to salvation.
Mafunzo ya Calvin pia yaongeza imani kuwa neema ya Mungu haizuiliki, bali mafunzo ya Arminian yasema kuwa mtu binafsi anaweza zuia neema ya Mungu. Neema isiyozuilika yapinga kwamba wakati Mungu anamwita mtu kwa wokovu, huyo mtu bila kuepa atakuja kwa wokovu.
