After resting on the seventh day, what did God do?

Answer

"And God blessed the seventh day, and sanctified it: because that in it He had rested from all His work
which God created and made." Verse 3.
NOTE-And inasmuch as this blessing and this sanctification of the day were a part of the making
of the Sabbath, as well as the resting upon the day, these also must have been done by Christ; for the
Sabbath was made by Him.
