Settling every Bible based question or studying every Bible based topic can hardly be resolved with a single verse every time, but there are times when a single verse is so clear and concise in what is being said, the point cannot be missed by any honest Bible student.
For example, take the question and topic of a God-ordained modern-day observance of the seventh-day Sabbath. Considering the fact that entire denominational movements revolve around a Sabbath day commandment observance, I’d say the answer to the situation is important. The truth of the matter is often blurred by the difference between God’s law for the nation of Israel and God’s law for the church, who is spiritual Israel, as a whole.
Support for a Sabbath commandment abounds in the Old Testament, but by the time the epistles to the church begin, there is no so much as a step to be found! Fact is, a single verse cannot be quoted from the entire New Testament that reveals God’s direct command for the Sabbath to be observed in the church as a whole, nor a single verse that warns about the lack of observing a seventh-day Sabbath. Furthermore, all scriptural evidence points toward the seventh-day Sabbath being annulled with the rest of the framework of Moses’ law. Because of this truth, Colossians 2:16 says, “So let no one judge you in food or in drink, or regarding a festival or a new moon or sabbaths,“, and the last time I checked the plural word of sabbaths contains any single day observance of a Sabbath.
The legal right to judge someone based upon the observance a Sabbath day, or the lack-thereof, was removed when the law of Christ replaced the law of Moses (Hebrews 8:7-13). Regardless of how an individual feels about it, the church as a whole is obligated to find our rest in Jesus (Matthew 11:28-30; Hebrews 3:12-19, 4:1-11) but not the 10 Commandments as a whole.
