Actually it is absurd to believe what you have just said. The sabbaths that were apart of the ceremonial system and the handwriting of ordinances were included because of the shadows of the old covenant. Jesus blotted out the shadows and therefore we no longer have to observe these days and feasts that were apart of the ceremonial system. The 7th day Sabbath was made before sin even entered the world and was made for man. It was not made for sacrifices and ordinances like the other sabbaths. It stands.
Stand it does, indeed, on every calendar. We still have a seven-day week and the seventh day is Saturday or, as some would have it, Shabbat.
God have the Sabbath to man. It was made before the children of Israel even existed. The 7th day was blessed and sanctified at the end of creation week. Jesus fulfilling the law does not mean that we dont have to abide by it anymore. He fulfilled it so we can understand it better. Why did he go through the trouble of explaining Sabbath keeping and explaining adultery and murder if we are not to bother with it anymore. If we love Jesus we will keep his commandments for love is the fulfilling of the law.
Please allow me to follow your circular reasoning. If Christ is love and love is the fulfilling of the law, then Christ has fulfilled the law and we cannot fulfill what Christ has already fulfilled. If not, then we are under obligation to keep to whole law and to keep it perfectly. This does not merely include keeping Shabbat, but keeping kosher and performing every ordinance given by God to His covenant people. Please show us where Jesus commanded anyone to keep Shabbat, much less how to do so.
When you are adopted are you still a gentile? Paul said that he was a jew not of the outer but the inner man or something close to that. If anyman be in Christ he is abraham's seed. He is a son of Abraham. He is of the house of Israel by adoption. He is no longer a gentile. The Sabbath is not for the jews but for man.
I am a Gentile and will be a Gentile until the day I die. Although I am part of that one new body in Christ composed of Jews and Gentiles and known as the church (Ephesians 2) it hardly means that I am a Jew and, therefore, obligated under the Mosaic covenant.
Sounds good but it is not biblical. We are told to enter into God's rest the way that God did from his. Did God rest from works to fulfill the law? No. God ceased from his work of creation on the 7th day. If we are to follow that example it means that we should also cease from our physical works.
Then Christ was in violation of God's sabbath because He healed (worked) on the Sabbath and did not cease from His physical works. You may well argue that Christ, being God, was an exception. However, if my neighbor suffers a heart attack on the Sabbath would you, if you were a doctor, be justified to stand idly by and let him die?
According to you we need not to put any effort into trying to fulfill the law when the scriptures plainly tell us that when we love we fulfill the law. It takes effort to resist the lusts of the flesh and hold on the Jesus. It takes effort to gain the victory over sin. Not by our own strength by his strength. But it is our willingless and effort to surrender to him and let him take over us.
If that is the case, then we will have earned our salvation through our efforts and salvation will be a matter of our efforts and not of God's grace. According to John 10:27-29 who holds who? I am quite certain that if it was up to me to hold onto Jesus, I would lose my grip. Where, in the Bible, does it say that it is up to us to hold onto Him?
