How do we know that Jesus offers true rest?

Jesus offers true rest because He guarantees the completion of the work of redemption, as mentioned in John 17:4, where He confirms to the Father that He has finished the work given to Him. This assurance is foundational to the believer's hope; it underscores that all burdens related to sin and the law have been borne by Christ on the cross. Therefore, coming to Jesus allows believers to enter into this rest, freeing them from the striving of trying to earn God’s favor through their own works.
