What does Hebrews say about the relationship between faith and entering rest?

The book of Hebrews makes a clear connection between faith and the ability to enter into God’s rest. It describes how the Israelites failed to enter the promised land due to their unbelief, which serves as a warning to believers today. Hebrews 4:2 asserts that the gospel was proclaimed to them, but it did not benefit them because they did not mix faith with it. Thus, entering into God's rest is contingent upon faith in Christ, who invites believers to lay down their own works and rely solely on His completed work for salvation. This relationship between faith and rest underscores the Reformed emphasis on grace through faith alone as the means of salvation.
