What does the Bible say about believing through grace?

Acts 18:27 emphasizes that those who believed did so through grace, highlighting that faith originates from God's divine grace rather than human effort or merit. Ephesians 2:8-9 elaborates on this concept, stating that by grace we are saved through faith, which is not of ourselves but a gift from God. This underscores the theological truth that grace is the very foundation upon which genuine belief and salvation are built. Without grace, belief would be unattainable, as sinners are wholly dependent on God's initiating grace to bring them to faith.
