|Jesus finished God’s work of redemption at the cross once and for all and only
the person who believes in Christ and his work, enters this rest.
Finished work, rest, Sabbath, peace, Christ, redemption, cessation of works, faith - these all are taken up into the concept of rest which was first announced at the end of creation week. It is difficult not to notice further connections, such as the “new creation” passages of the epistles (2 Cor. 5:17; Eph. 2:10). Likewise, it is doubtlessly beyond coincidence that it was on the sixth day of the week that Jesus finished God’s work of redemption (Mark 15:42).
Further, unlike the Mosaic priests who must “stand ministering daily and offering the same sacrifices which can never take away sins” (Heb. 10:11), Jesus “sat down,” having accomplished the work of redemption “once for all” (Heb. 9:12; 10:12). Redemption is done and rest may now be enjoyed. “No work allowed,” is the watchword of this new creation. “This is the year of Jubilee - by the work of his Son God has declared all debts canceled for all who believe!”
“Behold, now is the accepted time; behold, now is the day of salvation” (2 Cor. 6:2). The person who “does not work but believes on him who justifies the ungodly” (Rom. 4:5) enters this rest. It is a celebration of God’s work, a work taken up long ago and now accomplished in Christ. The invitation is to faith in Christ and his work that saves. Fred G.
