What does it mean to enter God's rest?

In Hebrews 4, the concept of rest is multi-faceted, referring both to the physical rest promised to the Israelites and a deeper, spiritual rest found in Christ. The author warns about the danger of failure to enter this rest due to unbelief, pointing to the need for faith in God's promises. This rest signifies a cessation from striving for salvation through works, embracing the assurance that we are accepted in Christ. By relying on God's grace, believers can experience true peace, as we no longer work to earn favor but rest in the sufficiency of Christ’s finished work on the cross.
