Then you observe something of your own creation. I don't have a Sabbath. I cannot create one nor can I sustain one.
The 7th day of the week is God's Sabbath. He made it, commanded its observance including keeping it holy, and I do that as best I can. The other six days of the week, exclusive of annual Sabbaths, are mine to do with as I choose.
It still amazes me that people can look outward through telescopes into an immense orderly universe, through microscopes into an equally magnificent ordered scheme of things, or just around them at all the things God has made, and, even though mankind has not and cannot even assemble the component elements of a bite of food, puff themselves up to think that the God can be trifled with. Then I remember that some things can only be understood by the doing of them, such as riding a bicycle, and yet again realize the seemingly unlimited patience God has with us.
But it's not unlimited. It ran out at the time of Noah. It ran out at Mt. Sinai. It ran out with the money changers in the Temple, and it ran out with some of the Pharisees. For 40 years, God gave manna to the Israelites wandering in the wilderness six days a week, but none on the Sabbath. Observing God's Sabbath was and is important to God. Considering our relative positions in the grand scheme of things, it had better be important to me too!
Excellent post and a sobering conclusion...
