What is the relationship between the gospel and God's promises?

The gospel encapsulates God's promises to His people, reflecting the covenant established with Christ as their mediator. As highlighted in Acts 13:32, the gospel is 'glad tidings' concerning the promises made to the fathers, revealing God's faithfulness through history. The promises encompass not just momentary blessings but the assurance of eternal life and union with Christ, as seen in Romans 4:16. This union entails that all spiritual blessings flow from being in Christ, confirming that the gospel is inherently about God's faithful promise to His chosen people.
