How do we know Jesus fulfills the promise of rest?

The promise of rest mentioned in Hebrews is fulfilled in Jesus Christ, who leads His chosen people into the eternal rest that God has promised. While the Israelites wandered in the wilderness due to unbelief and inability to enter the promised land, Christ as our Joshua leads us into the ultimate promise. The writer of Hebrews draws a clear connection between the rest offered by Joshua and the eternal rest found in Christ, asserting that Jesus' finished work on the cross provides assurance that believers can enter this rest. This theological concept is deeply rooted in the understanding of God’s covenant promise to His people.
