I follow the Bible not doctrine however the adventists are right about Israel, secret rapture and the Sabbath. The Bible is clear especially in the New testament who Israel is. From Jesus Himself to the apostles, they make it clear we are all Israel if we accept Jesus as Messiah and God. In the New Testament, the name Israel not only applies to Jesus Christ, but also to those who are born in Christ—His Church! In other words, all true Christians are now God’s spiritual Israel. Israel is no longer a physical place on earth, it is spiritual. It about the heart. That is why we can all be Israel even though most of us aren't Jewish genetically.
The secret rapture is not biblical. The following passage is often quoted to support the secret rapture:
"For as in the days before the flood, they were eating and drinking, marrying and giving in marriage, until the day that Noah entered the ark, and did not know until the flood came and took them all away, so also will the coming of the Son of Man be. Then two men will be in the field: one will be taken and the other left. Two women will be grinding at the mill: one will be taken and the other left. Watch therefore, for you do not know what hour your Lord is coming" (Matthew 24:38-42).
This text does not prove a secret rapture. It merely points out that at the return of Christ, some will be saved and others will be lost.
The dispensationalist view that the Antichrist will arise after the secret rapture is also not in line with the teaching of Scripture. The Bible clearly teaches that this power will arise from the Church, not after the Church:
"Little children, it is the last hour; and as you have heard that the Antichrist is coming, even now many antichrists have come, by which we know that it is the last hour. They went out from us, but they were not of us; for if they had been of us, they would have continued with us; but they went out that they might be made manifest, that none of them were of us" (1 John 2:18-19).
The state of Israel that was established in 1948 is meaningless biblically. Its just a country like any other. Israel as a missionary nation of God ceased to mean anything two thousand years ago. As I pointed out above, Israel is now spiritual not physical. Being Jewish is no longer about being a physical descendant of Abraham. A real Jew in the sight of God is anybody—Jew or Gentile—who has personal faith in Jesus Christ! Paul sums it up well. He wrote, “Behold, thou art called a Jew, and restest on the law, and makest thy boast of God ... For circumcision verily profiteth, if thou keep the law: but if thou be a breaker of the law, thy circumcision is made uncircumcision. Therefore if the uncircumcision [Gentiles] keep the righteousness of the law, shall not his uncircumcision be counted for circumcision? ... For he is not a Jew, which is one outwardly; neither is that circumcision, which is outward in the flesh: But he is a Jew, which is one inwardly; and circumcision is that of the heart, in the spirit, and not in the letter; whose praise is not of men, but of God” (Romans 2:17, 25, 26, 28, 29).
We know physical Israel ceased to be a chosen nation because ceremonial law ceased to mean anything and the veil that separated the Holy and Most Holy rooms in the earthly temple ripped in two from the top to bottom (Matthew 27:50-51), signifying that the temple no longer held meaning after Jesus' death. The Jewish sacrificial system with its rites and ceremonies had ended. Atonement for sins was only available through Christ, and the symbolic practices had been fulfilled through Christ. The earthly sanctuary and its ceremonial feasts, pointed to Christ and His ministry. It was also a miniature enactment of the much greater ministry of Christ in the heavenly sanctuary, of which the earthly sanctuary was merely “a figure for the time then present” (Hebrews 9:9). The earthly sanctuary was a copy of the heavenly one. Christ entered the heavenly sanctuary that was not built by human hands after His resurrection and ascension into heaven.
"We have such an high priest...in the heavens; A minister of the sanctuary, and of the true tabernacle, which the Lord pitched, and not man" (Hebrews 8:1-2).
"For Christ is not entered into the holy places made with hands, which are the figures of the true; but into heaven itself, now to appear in the presence of God for us" (Hebrews 9:24).
The Sabbath is not Jewish either is it? It is called “the sabbath of the Lord,” and it is never called “the sabbath of the Jew”. Jesus also taught that “the sabbath was made for man” (Mark 2:27). Adam and Eve were the only two people who existed when God actually established the Sabbath. There were no Jews in the world until 2,000 years later, so it was never meant just for the Jews. Jesus uses the term “man” in the generic sense, referring to all mankind. The same word is used in connection with the institution of marriage that was also introduced at creation. Certainly no Christian can believe that marriage was made only for the Jews.
Satan's strategy is to take as many people as he can away from biblical truths. He has successfully planted dangerous lies in Christian theology, that have been unwittingly hatched, adopted and nurtured by most Christian churches. This parasite always has and is pushing out Bible truth with a bigger-than-life-deceptions. Sadly, these adopted falsehoods are growing fat with attention while true biblical doctrine and interpretations of prophecy are starving with neglect.
As Christians we should take the Word of God up and above any Christian doctrine that goes against His Word.
