Why not just take 2 days for the Sabbath, Saturday and Sunday and spend time with other Christians, or do Sabbath on Friday like Islam. Why is the Sabbath so important, between God and His people. What would you tell someone to enlighthen them on this question?

If a person rests on the Sabbath, would it be wrong of them to also go to church on the sunday?

Depends on the person's motive. There is nothing wrong per se with going to church on Sunday, though it is mildly akin to entering a place of amusement or a tavern, etc. If you are entering there, not for your own selfish reasons but to find and help others who are there, there is no problem.

Jesus ate with sinners and prostitutes. It did not corrupt His pure mind to do so, and it need not corrupt us either if we remain connected to Him. Go to that church on Sunday and preach!

If, on the other hand, one attends Sunday church strictly for political reasons, or to give the impression that one keeps Sunday as the sabbath, or for some other selfish or anti-biblical purpose, "be sure your sin will find you out."

God reads the heart.

Ask that person if he or she would like to celebrate their wedding anniversary and/or birthday on a different day, just because others thought it was a good idea. Is their special day really any different from another day? Why not just celebrate it a different time...or not at all?

If someone is willing to disregard Sabbath observance now, think of how much easier it will be for them to make the same decision when under threat of losing their job or their life.

If it be wrong to go to church on Sunday, too, would it be wrong to go to church on Wednesday? Or Sunday evening? Or is it wrong to go to any other church on any day?

Could that problem be solved by recogniseing "church" as the body of Christ rather than as a building which you can be inside and which you leave after your 2 hours of sabbath service are up?

Not to complicate the issue, but I once went to a large church that had four services, one of which was on Saturday.

The biggest flaw I see in discussions like these is how man starts to look at his own understanding above God's. Who are we to debate the true virtue of God's laws? Scripture clearly defines God's law regarding obedience to the Sabbath, it is left to man to freely obey it. God can wink at our ignorance, but once a person willingly rejects or intentionally breaks any of the commandments, they will be held accountable.

JCS your last post didn't really say anything. Can you be more specific?

Furthermore, there are no post-resurrection injunctions to keep the Sabbath, which was part of the Jewish law, and early Christians almost immediately began meeting on Sunday as well as Saturday, as shown by the following quote from Justin Martyr, who died AD 165:

"And we afterwards continually remind each other of these things. And the wealthy among us help the needy; and we always keep together; and for all things wherewith we are supplied, we bless the Maker of all through His Son Jesus Christ, and through the Holy Ghost. And on the day called Sunday, all who live in cities or in the country gather together to one place, and the memoirs of the apostles or the writings of the prophets are read, as long as time permits; then, when the reader has ceased, the president verbally instructs, and exhorts to the imitation of these good things. Then we all rise together and pray, and, as we before said, when our prayer is ended, bread and wine and water are brought, and the president in like manner offers prayers and thanksgivings, according to his ability, and the people assent, saying Amen; and there is a distribution to each, and a participation of that over which thanks have been given, and to those who are absent a portion is sent by the deacons. And they who are well to do, and willing, give what each thinks fit; and what is collected is deposited with the president, who succours the orphans and widows and those who, through sickness or any other cause, are in want, and those who are in bonds and the strangers sojourning among us, and in a word takes care of all who are in need. But Sunday is the day on which we all hold our common assembly, because it is the first day on which God, having wrought a change in the darkness and matter, made the world; and Jesus Christ our Saviour on the same day rose from the dead. For He was crucified on the day before that of Saturn (Saturday); and on the day after that of Saturn, which is the day of the Sun, having appeared to His apostles and disciples, He taught them these things, which we have submitted to you also for your consideration.

This is from Justin's "First Apology", dated around AD 150-155. Since the dating of the NT books ranges from AD 45 - AD 120, depending on your sources, this is not far off the beginnings of Christianity.
