Genesis 2:2, 3 says, “And on the seventh day God ended His work which He had done, and He rested on the seventh day from all His work which He had done. Then God blessed the seventh day and sanctified it, because in it He rested from all His work which God had created and made” (Genesis 2:2, 3).
Why did God choose to create the heavens and the earth in six days, and then rest on the seventh day?
He used it to set a pattern for the Jewish work week, but why not create in nine days, and rest on the tenth?
We can only say that He had His own reasons for doing so, and perhaps we shall discover the reason later in the Scriptures, or when we get to heaven itself.
What do you think?
