Why is God's promise to Israel relevant for Christians today?

The promise God made to Israel in Exodus 3:21-22 that they would 'not go empty' serves as a type and shadow of the spiritual reality Christians experience through Christ. Just as God assured Israel that their needs would be met in their exodus from Egypt, Christians are assured that their needs for salvation and eternal life are secured in Christ. This reflects God's unwavering commitment to His elect, ensuring they receive grace upon grace. Romans 8:32 reminds us that if God did not spare His own Son, He will graciously give us all things, affirming God's ongoing provision and faithfulness to His people.
