What is the rest of faith mentioned in Hebrews?

Hebrews 4 presents the concept of 'rest' as a spiritual state where believers find peace through faith in Christ. This rest signifies freedom from the burdens of legalistic righteousness and the assurance that through Christ's finished work, believers are justified and have peace with God (Romans 5:1). The 'rest' refers to the spiritual assurance that God has completed His work of redemption. It mirrors the rest of God after creation, indicating that just as God ceased from His works, believers cease from striving for salvation through works. This rest is an ongoing experience of peace and confidence that arises from a relationship with Christ, who is the ultimate source of true rest.
