Not far from where I live there’s a Messianic Fellowship building of worship where both Messianic Jews and Christians congregate on the sabbath. These Christians observe Jewish holy days. One of them owns a 2nd hand shop and always closes it on certain feast days like the Feast of the Trumpets. These so called Christians are similar to those Gentiles in the New Testament who were referred to as devout god-fearers. They put themselves under the Jewish law and would follow synagogue teachings. The Bible tells us that these God fearers were not saved (born again). Cornelius and Lydia are two examples. They were devout and worshiped God, yet Peter and Paul had to present the Gospel of Jesus Christ to them. They came to believe and were later baptized. It is not enough to be religious or even to believe in the existence God and have a form of worship, for even demons believe in the one true God and tremble. They of course do not posses salvation.
Why would any Gentile, especially those who claim to be Christian, want to put themselves under the law in this age of grace? The law was never meant for them. It was given to the nation of Israel to show the Jews what sin is and how far they have fallen.That man cannot save himself. He needs a Messiah. The law was never meant to be permanent as no one can keep the whole law. It was to pave the way for God’s Son, the Lord Jesus Christ who alone saves us.
Most Messianic Jews still keep the Old Testament practices such as the sabbath, kosher laws, circumcision, holy days, etc. This is mixing the Old Covenant with the New Covenant. The Bible tells us the two are mutually exclusive. They no more mix than do oil and water. Jesus Christ fulfilled the law. He paid our sin debt in full. In Christ there is neither Jew nor Greek. We are all one. To accept Christ as Savior and at the same time adhere to law keeping is offensive to God. Its denying Christ’s complete atonement at the cross. God sent His only Son into the world who is now our High Priest forever. His blood alone forgives sins. If you call yourself a Messianic Jew because you believe that Yeshua is the Messiah, then you cannot continue with the Old Covenant.
It begs the question: Have Jews ever asked themselves why there has been no Temple since 70 AD? Why hasn’t God brought back animal sacrifices? How do they handle the fact that they haven’t been able to deal with their sins? Why is there no more physical priesthood in the line of Aaron? The answer is simple. Christ fulfilled all that through His perfect blood sacrifice. He satisfied all the demands of the law. The main function of a priest was to act as mediator between man and God.To kill animals and spill their blood to cover sin.Yet, Christ in this age of Grace is our sole Mediator.With the shedding of Christ’s blood we have remission of sins. Therefore, the temple is obsolete because now the body of the born again believer in Jesus Christ is a temple where the Holy Spirit indwells
Believe on the Lord Jesus Christ and you shall be saved. This is the New Covenant. Christ did it all for us, By accepting Him as Messiah we have peace with God. Salvation is the work of God, not the work of man. Its a free gift. Accept it. Don’t try to earn it through a myriad of works, rules and law keeping. You’ll never make it.
