Covenants are built on promises. The author of Hebrews emphasizes that the new covenant is founded on something far superior to the old. What makes these promises 'better'?
The crucial phrase here is 'established upon better promises.' Benson explains that the promises of the old covenant often pertained to temporal blessings—length of days, prosperity, national privilege. While the promise of eternal life was present, it wasn't the primary focus or as clearly revealed. The new covenant, mediated by Christ, is founded on 'better promises' that are primarily spiritual and eternal. These aren't just earthly benefits but heavenly realities. Barnes points out that the new covenant's promises direct the mind to heaven and offer the hope of immortal life. This isn't just a change in the object of the promises, but in their nature and , being secured by Christ's perfect work and guaranteed by His Spirit.
