What does Christ creating the heavens and the earth in 7 days have to do with the plan of redemption? Your assertion was that the first part of Genesis is the basis of the rest spoken of in Matthew 11 and Hebrews 4. The basis of something doesn't need to be identified by something else.
However true it may be, name-dropping Jesus into the creation narrative does nothing to support your claims.
Even the 2 givings of the law to Israel itself distinguish creation from redemption right in the 4th commandment. They do, without a doubt, come from the same Hand of love and mercy. But creation is not the new (re-)creation. Eden is not Calvary. Genesis 1 is not Colossians 1. And the 7-th day Sabbath is not the Atonement.
Tyndale was so certain of that that he felt compelled to create an entirely new English word for it.
Loading progressive revelation onto Genesis 1 and 2 is just putting the cart before the horse.
There are many exceptions to the rule, but the reason the vast majority of Christians won't consider keeping the original, literally expressed 4th commandment is either 1) tradition, or 2) dread of controversy/inconvenience.
When Sunday was widely believed by Protestants to be the object of the 4th commandment, no one objected to at least a modicum of it's observance.
But now that the proliferation of Bible study material in the media and on the Internet has nearly all non-Catholic scholars finding that position embarrassing to claim as sola scriptura, either the 4th or all ten commandments are under fire and sacrificed to spiritualism or declared ecclesiologically obsolete. Either views are entirely post-modern. Your believing grandparents would never have bought it.
And, as I said before, I can't spend much time on a one-dimensional discussion of this subject. If we can't comprehensively address each other's concerns, then we might as well just copy-and-paste old, existing thread contents.
The spiritualization of the 4th commandment is an objection that has been thoroughly exhausted here. Just search for Hebrews 4 if you'd like to read it.
