Christ, as we well know, is the great Creator. He is the wisdom of God, and the power of God. “For in Him were all things created, in the heavens and upon the earth, things visible and things invisible, whether thrones or dominions, or principalities or powers; all things have been created through Him, and unto Him; and He is before all things, and in Him all things consist” (Col. 1:16, 17, R.V.). “Without Him was not anything made that was made” (John 1:3). When the record says that in six days God made the heavens and the earth, it means God in Christ, for Christ is the only manifestation of God that is known to men. Therefore, also, we know that it must have been Christ who rested upon the seventh day, after completing the work of creation, and that it was Christ who blessed the seventh day, and sanctified it. Thus the Sabbath day is in an emphatic sense the “Lord's day.”
Why was the Sabbath made? “The Sabbath was made for man” (Mark 2:27). It is for him, in the sense that it is not against him. It is not an arbitrary thing imposed upon man,—something for him to keep simply because God says so,—but something that is given him for his help. It is a blessing that God has bestowed upon him. It is among the “all things that pertain unto life and godliness” (2 Peter 1:3), which His divine power has given unto us.
