Millions of people in Christendom are completely unaware of the fact that they are not amenable the 10 commandments. The lack of knowledge and understanding goes even to the extent that many of these individuals confuse the first of day of the week with the seventh day of the week by referring to it as the “Christian Sabbath.” But ignorance does not change reality, and reality says that the first day of the week is not referred to as the “Christian Sabbath” in any single verse of the New Testament.
The seventh day Sabbath had a purpose for the children of Israel (Deuteronomy 5: 2-4, 12, 15) and that purpose came to an end when the Law of Moses was replaced with the Law of Christ (Galatians 3:11, 24-25; Hebrews 8:6-7). The rest for God’s people under the New Covenant is not a single day of the week – it is the laborious induced hope of a continual reward of rest in the heavenly presence of God (Hebrews 4:8-11).
Go ahead and enjoy some physical rest. There is nothing wrong with resting in and of itself. But when it comes to resting (or worship) there is no need to confuse others when it comes to the relationship of the 10 commandments and the New Covenant by referring to the first day of the week as any sort of “Sabbath” other than a personal one that is not bound as a commandment upon the church as a whole by God (Romans 14:5-6).
“Come to Me, all you who labor and are heavy laden, and I will give you rest. Take My yoke upon you and learn from Me, for I am gentle and lowly in heart, and you will find rest for your souls. For My yoke is easy and My burden is light.”” (Matthew 11:28-30 NKJV)
