If a Christian can lose salvation, then Romans 8:30 is in error, because God could not guarantee glorification for all those whom He predestines, calls, and justifies.
Kama Mkristo anaweza kuupoteza wokovu, basi Warumi 8:30 ina makosa, kwa sababu Mungu hakuweza kuwahakikishia kutukuzwa wale wote ambao Yeye aliwachagua, waito, na kuwafanya haki.
