Read Luke 18:7 Using Other Translations
And shall not God avenge his own elect, which cry day and night unto him, though he bear long with them?
And will not God give justice to his elect, who cry to him day and night? Will he delay long over them?
Even he rendered a just decision in the end. So don’t you think God will surely give justice to his chosen people who cry out to him day and night? Will he keep putting them off?
