יהוה, the God of the Bible, made the Heaven and the Earth in six days, and when the Heaven and the Earth were finished, and all the host of them, יהוה commanded Adam, his descendants, and all the families of the Earth to obey, comply with, and conform to, as LAW, the observance of the SEVENTH DAY as a day of REST to observe and to honor the memory of Him for ALL HIS “WORK”—HIS CREATION—which He, יהוה, created and made.
In order to keep the law of the SABBATH, we must keep it based on the DAY commanded by יהוה, the God of the Bible. His DAY is indicated by means of the SUN—from sunset to sunset (Genesis 1:5).
In Genesis 2:2-3, יהוה blessed the SEVENTH DAY. The “SEVENTH” DAY is the SABBATH of יהוה. And in it, the Sabbath, NO ONE is to do “any” work (Exodus 20:8-10). It is a “holy” day devoted entirely to reflecting upon and giving “exclusive” honor to יהוה.
The observance of the SABBATH is a “direct” indication to יהוה that we are remembering Him for the stunning beauty of all His WORK, which He produced. Keeping the SABBATH is also a “direct” manifestation to יהוה that we are reflecting upon Him for the startling and staggering symmetry of all that He designed and constructed.
The SABBATH is a “SIGN” between only יהוה and you. And observing it is a testimony to יהוה that we are honoring Him for the amazing elegance or gracefulness of ALL that He formed and fashioned. Our commemoration of this day serves as proof to יהוה that we are esteeming Him for the marvelous balance that He gave the universe.
