It is illuminating to associate with the first act of Creation the second great act of God in history. It was on Friday after noon that Christ completed His redemptive mission on this earth. John reports the last words that Jesus pronounced on the cross: “When Jesus had received the vinegar, he said, ‘It is finished’; and he bowed his head and gave up his spirit” (chap. 19:30, R.S.V.).
Some might say that it was just coincidental that Christ completed His work of redemption on Friday afternoon and that He pronounced those significant words “It is finished” just as, to use Luke’s words, “the Sabbath was beginning” (Luke 23:54, R.S.V.). We know, however, that in God’s plan nothing really happens accidentally. There is a purpose and a reason behind what our human eyes might see as simple coincidence. Luke emphasized specifically in his inspired re port that when Christ died on the cross, “It was the day of Preparation, and the Sabbath was beginning.” In the follow ing verse the same Gospel writer describes how the women meticulously placed Christ’s body at rest in the tomb, and then, we read in verse 56, “On the sabbath they rested according to the commandment.” Indeed, Christ completed His second great act as the Sabbath was beginning, and having said, “It is finished,” He took time to rest on the Sabbath.
Jesus kept the Sabbath perfectly. He was the only one who was sinless.
