Can we be sure we can trust God to keep his promises to us? What about God’s promises to his chosen people, Israel? Have God’s promises failed? This week we see from Romans 9:1-33 how God’s promises have not failed, nor is he unjust, because salvation depends on God showing mercy to those he has chosen. Far from undermining our confidence, understanding God’s merciful choice humbles us and gives us a deeper confidence in our sovereign God.
