How does God's power relate to His grace?

In the sermon, the preacher reveals that God's declarations of 'I will' are firmly grounded in His omnipotent authority, meaning that when God purposes something, it will surely come to pass. This is indicative of the power inherent in His grace. For example, the repeated phrase 'I will allure her' highlights God’s determination to draw His people to Himself. This assurance provides comfort to believers, reinforcing that our salvation and sanctification are secured by God’s powerful grace, not our own efforts. Thus, the power of grace is both a comfort and a guarantee of God's faithfulness.
