I have a valid question for you.
For those of us ( me included) who do not observe the biblical Sabbath... Saturdey... or more correctly as the Jews did of days of old... Friday Sundown or 6PM to Saturday Sundown to 6 PM is it your belief that none shall be saved.
Please answer yes or no.
Bearimg in mind, while
The Sabbath day that the bible speaks about is Saturday, the seventh day of the week (Genesis 2:2-3, Leviticus 23:2-3). The Jews have always considered a day to be the interval from sunset to sunset, and they have always observed the Sabbath from Friday evening until Saturday evening. Modern Jews continue the tradition of observing a holy day of rest on the Sabbath (Shabbat in Hebrew) from sunset Friday until nightfall Saturday. The Old Testament law prohibited doing any work on the Sabbath, and one could receive the death penalty for breaking this law (Numbers 15:32-36).
But, enter Jesus...
Jesus observed the Sabbath (Luke 4:16) and never suggested a change to Sunday. He did, however, reject a strict legalistic interpretation of the Old Testament commandment. He said Sabbath observance was not a duty that mankind owed to God. Rather, God made the Sabbath as a day of rest for mankind's benefit (Mark 2:27). Jesus and His disciples did not observe the strict Jewish rules against doing any work on the Sabbath (Matthew 12:1-14, Mark 2:23-28, 3:1-6, Luke 6:1-11, 13:10-17, 14:1-6, John 5:1-18).
Does the non Saturday observance of the Sabbath mean that those of us doing so will not be saved?
Salvation is a private issue, handled by God in relation to humanity on an individual bases. All who consistently reject truth, which they know and understand to be so, will be lost. God alone knows exactly who that is.2Th 2:1 Now we beseech you, brethren, by the coming of our Lord Jesus Christ, and by our gathering together unto him, 2 That ye be not soon shaken in mind, or be troubled, neither by spirit, nor by word, nor by letter as from us, as that the day of Christ is at hand. 3 Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition; 4 Who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God. 5 Remember ye not, that, when I was yet with you, I told you these things? 6 And now ye know what withholdeth that he might be revealed in his time. 7 For the mystery of iniquity doth already work: only he who now letteth will let, until he be taken out of the way. 8 And then shall that Wicked be revealed, whom the Lord shall consume with the spirit of his mouth, and shall destroy with the brightness of his coming: 9 Even him, whose coming is after the working of Satan with all power and signs and lying wonders, 10 And with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved. 11 And for this cause God shall send them strong delusion, that they should believe a lie: 12 That they all might be damned who believed not the truth, but had pleasure in unrighteousness.
When however, this issue of truth or error regarding God's Sabbath is agitated on a global scale, as it surely will and already has many been times over in more localized settings, the situation will change. When in fact the spurious man made sabbath of Sunday sacredness is exalted above God's law and Sabbath by human laws in direct defiance of the same, those choosing the former over the latter will be in a lost condition. The issue of worshipping God or self, in relation to submitting to His or human commands, will be the final and simple test for humanity. God will make the final choice as simple for humanity as possible, right before He returns unto execution of judgment. Choose submission to authority based upon His Holy scriptures, or choose submission to the usurped authority of fallen humanity under the guiding influence and direction of the evil one Himself.
So the simple answer is no, not yet. But when truth and error are simply and conclusively juxtaposed by the will of God Himself before all, shortly before His return, every decision will be made with eternal consequence. Choose submission to God and His word or authority, or choose submission to fallen humanities word or authority. Then the end. As the prophecies of the bible have clearly delineated for us in the book of Revelation especially.
