What does the rest spoken of in Hebrews refer to?

In Hebrews, the promise of rest symbolizes the ultimate peace and security found in Jesus Christ. This rest is not just a physical rest but a deep spiritual assurance that believers enter through faith. Hebrews 4:1-2 warns us not to fall short of this promise due to unbelief, but rather to actively enter into the rest that Christ offers. This rest reflects the fulfilled work of Christ in defeating our enemies, sin and death, and it is a rest that grants us peace amidst life's struggles. Believers can embrace this rest, knowing their future is secured in Him.
