After working through the text of Leviticus 23:1-3 Allen Ross concludes:
“So then, the primary application of this passage must be worded in light of the fulfillment of the law in Christ. In expounding the text of Leviticus the expositor may declare that the believer shows allegiance to the covenant by sharing the Sabbath rest of God–but for the Christian that means living one’s entire life in the rest that Christ provided. Christians may have grown accustomed to going to church on Sunday morning, but that is not keeping the Sabbath. Making one day more holy than another is not living in the fulfillment of the promises or according to the teaching on sanctification. When Christians truly understand what it means to sanctify their lives to God–their time, their talents, their activities, their priorities–then they will find greater blessing and greater fulfillment in their Christian lives, and then they will begin to enjoy what God has planned in his Sabbath rest” (Allen P. Ross, “Holiness to the Lord: A Guide to the Exposition of the Book of Leviticus,” 406).
