Then he goes into the New Testament..
The Sabbath and God's "rest" are not mutually exclusive, but rather, they are complementary. Insofar as keeping the seventh day Sabbath expresses and helps maintain belief in God (see below), it contributes to the experience of entering God's rest. Therefore, when God offered his "rest" to the Israelites, he offered the Sabbath along with it. The Sabbath was supposed to be part of God's "rest" and there is no indication in the Bible that this has changed.
At first glance, Colossians 2:16-17 could appear to contradict the conclusion which I reached from exegesis of Hebrews 4. Colossians 2:16-17 reads:
2:16 Therefore do not let anyone condemn you in matters of food and drink or of observing festivals, new moons, or sabbaths.
2:17 These are only a shadow of what is to come, but the substance belongs to Christ.
In verse 17, "shadow" means "temporary type." So does this mean that the "sabbaths" mentioned in verse 16 functioned as temporary types?
The issue here is ritual observance of special holy days. "Festivals, new moons, or sabbaths" inverts the order found in Numbers 28-29, where the calendar of ritual offerings on holy days includes offerings on Sabbaths (Num 28:9-10), new moons (Num 28:11-15) and festivals (Num 28:16-29:40). These offerings were part of the Israelite worship system. But it was the rituals performed on the days, not the days themselves, which functioned as the types. Notice that in Colossians 2:17, the pronoun "These" identifies the shadowy things as the list in verse 16: "food and drink or of
observing festivals, new moons, or sabbaths" in verse 16. Along with food and drink, which in this context must be religious in nature because they have typological significance, it is ritual
observance(10) of the festivals, new moons, and Sabbaths which constitutes the "shadow"/type; it is not the days themselves. There is no evidence that new moon days, for example, had typological significance of their own; it was the special sacrifices offered on new moon days (Num 28:11-15) which served as a "shadow."
In Colossians 2:16-17, Paul affirms the same basic message which was decided at the Jerusalem council (Acts 15): People do not need to practice the Jewish rituals in order to be Christians. The rituals were historical types pointing forward to the better, truly efficacious ministry of Jesus Christ, which has already begun and to which our focus should be directed....As a sign of the on-going dependence of human beings upon their Creator and his work, the seventh day Sabbath continues to have significance for the "new covenant." The fact that the Sabbath functioned during the "old covenant" period does not mean that the Sabbath became obsolete with that covenant. Rather, there is a sense in which the significance of the Sabbath is restored under the "new covenant."
When God reaffirmed the Sabbath for Israel, the Sabbath was more than a commandment; according to Exodus 31:13,17 (cp. Ezek 20:12), the Sabbath functioned as a sign of the covenant relationship by which he sanctified the Israelites. This function applied to Israel a principle which had been inherent in the Sabbath since Creation. On the seventh day of Creation, God sanctified the Sabbath (Gen 2:2-3), a unit of time. Why? In order to affect those who observe this special time. How would they be affected? They would emulate their holy Creator and acknowledge their on-going connection with him. Because they would belong to God, who is intrinsically holy, they would gain holiness from him. In other words, the Sabbath would be a sign that God makes people holy, just as God explicitly said in Exodus 31:13 with particular reference to the Israelites. From the beginning, his desire has been for all people to enjoy a holy relationship with him.
The divine-human relationship signified by the Sabbath is one in which human beings are dependent upon God and his work. Thus, those who rest on the Sabbath acknowledge ". . . that I, the LORD, sanctify you . . ." (Exod 31:13) and "that in six days the LORD made heaven and earth" (vs. 17). The Sabbath is not simply the immovable "birthday of the world"; it recognizes the dependence of the world, and more particularly the human beings who have dominion over the world, on God who created the world....
