What does it mean to rest in Christ's finished work?

Resting in Christ's finished work speaks to the belief that His sacrifice is entirely sufficient for our salvation, eliminating the need for any additional works or efforts on our part. This concept is rooted in Hebrews 4:9-10, which refers to a 'Sabbath rest' that exists for the people of God, highlighting that true rest is found when we cease from our striving and trust wholly in Christ's completed work on the cross. The notion of resting in Christ is vital for understanding grace; it reassures believers that their acceptance before God is based purely on His grace and not on human merit. Therefore, true peace and assurance come from relying on what Christ has accomplished on our behalf.
