Do you believe God knows the end from the beginning? I do. God knew that Israel would never be a beacon to the remainder of the World's population. If the Sabbath was to be spread to all it would have to be done by Him. Many of the verses found in Isaiah have to be taken with a grain of salt. For instance, Is 65 tells us the righteous will live to be over 100. Those born will not die and the unrighteous will not live to be 100. Here, read it for yourself:
“See,
I will create
new heavens and a new earth.
The former things will not be remembered,
nor will they come to mind.
18 But be glad and rejoice forever
in what I will create,
for I will create Jerusalem to be a delight
and its people a joy.
19 I will rejoice over Jerusalem
and take delight in my people;
the sound of weeping and of crying
will be heard in it no more.
20 “Never again will there be in it
an infant who lives but a few days,
or an old man who does not live out his years;
the one who dies at a hundred
will be thought a mere child;
the one who fails to reach[a] a hundred
will be considered accursed.
“See, I will create
new heavens and a new earth.
The former things will not be remembered,
nor will they come to mind. Yet we see in Is 66:24 And they will go out and look on the dead bodies of those who rebelled against me; the worms that eat them will not die, the fire that burns them will not be quenched, and they will be loathsome to all mankind.”
Which is it Delvianna? will we not remember, or will we be reminded every week of the result of sinful man? Was God really depending on Israel to be a beacon of the "Sabbath truth" as declared by Isaiah.
How can people teach others to keep something they themselves cannot keep?
So, according to you, the commandment was there, but because of the circumstance, it was ignored, and God didn't hold them responsible. Does that make any sense?
What part of the law, revealed at Sinai, were they responsible for observing?
5 because Abraham obeyed me and did everything I required of him, keeping my commands, my decrees and my instructions.”Gen26:5
Where do you see anything in that verse that would instruct Abraham to observe the Sabbath? Abe was given explicit instructions, but nothing about the Sabbath. Wouldn't you think that something Sabbath observers deem so very important, God would reveal the command in just a few words, along with the other commands He gave Abe?
