Your focus is on "signs" to determine the "covenant" that you should adhere to. I am not arguing against signs as you are suggesting, but I am disagreeing with your dogged argument for the understanding today of a "new" and an "Old" covenant theology. It is based on a poor understanding of the scholars who translated the source text into the "English" language that we both use as our go to source to learn about God. Sadly we read about a "new" covenant in the NT, but the source text is speaking metaphorically of a "new coat of paint" which refreshes the old worn out look, so to speak, of the original covenant since Christ did not come to change the "law" and the prophets as they all pointed to His coming. Christ came to confirm the original covenant from before His time, and to refurbish the means of redemption.
Today we have many "goats" within the body of Christ, without having circumcised their hearts of the unrequired excesses that they hold dear to themselves.
Christ warned us about these things when He said: -
Mark 13:21-23: - 21 "Then if anyone says to you, 'Look, here is the Christ!' or, 'Look, He is there!' do not believe it. 22 For false christs and false prophets will rise and show signs and wonders to deceive, if possible, even the elect. 23 But take heed; see, I have told you all things beforehand.
Isaac was the confirming sign for Abraham, that God's covenant with him was true and would come to pass.
The "Promised Land" of Genesis 15:17-21 was a sign to the descendants of Abraham, that in the future they would inherit the whole earth, which is also the sign repeated in the NT as confirmation of our salvation.
(An aside: - We should remember that the sign of the Promised Land was for a discrete period of time, which began when the Israelites crossed the River Jordan to enter and ended because of their continual idolatry in 70 AD when God caused the Israelites to be scattered to the four corners of the planet in preparation for the next phase of the Summer season harvest.)
The confirming sign that Christ gave us for this time is this: -
Luke 21:10-19: - 10 Then He said to them, "Nation will rise against nation, and kingdom against kingdom. 11 And there will be great earthquakes/turmoil/commotions in various places, and famines and pestilences; and there will be fearful sights and great signs from heaven. 12 But before all these things, they will lay their hands on you and persecute you, delivering you up to the synagogues and prisons. You will be brought before kings and rulers for My name's sake. 13 But it will turn out for you as an occasion for testimony. 14 Therefore settle it in your hearts not to meditate beforehand on what you will answer; 15 for I will give you a mouth and wisdom which all your adversaries will not be able to contradict or resist. 16 You will be betrayed even by parents and brothers, relatives and friends; and they will put some of you to death. 17 And you will be hated by all for My name's sake. 18 But not a hair of your head shall be lost. 19 By your patience possess your souls.
CharismaticLady do you possess patience?
You cannot put new wine into old wine skins. That is what you are trying to do by saying the New Covenant is actually a continuation of the Mosaic covenant's Ten Commandments.
I don't know what you've read in this thread, but did you know that Ismael represented the Ten Commandments, not Isaac.
Galatians 3
17 And this I say,
that the law, which was four hundred and thirty years later, cannot annul the covenant that was confirmed before by God in Christ, that it should make the promise of no effect.
Galatians 4
21 Tell me, you who desire to be under the law, do you not hear the law? 22 For it is written that Abraham had two sons: the one by a bondwoman, the other by a freewoman. 23 But he
who was of the bondwoman was born according to the flesh, and he of the freewoman through promise, 24 which things are symbolic. For these are the two covenants: the one from Mount Sinai which gives birth to bondage, which is Hagar— 25 for this Hagar is Mount Sinai in Arabia, and corresponds to Jerusalem which now is, and is in bondage with her children— 26 but the Jerusalem above is free, which is the mother of us all. 27 For it is written:
“Rejoice, O barren,
You who do not bear!
Break forth and shout,
You who are not in labor!
For the desolate has many more children
Than she who has a husband.”
28 Now we, brethren, as Isaac
was, are children of promise. 29 But, as he who was born according to the flesh then persecuted him
who was born according to the Spirit, even so
it is now. 30 Nevertheless what does the Scripture say? “Cast out the bondwoman and her son, for the son of the bondwoman shall not be heir with the son of the freewoman.” 31 So then, brethren, we are not children of the bondwoman but of the free.
We are not under the Mosaic law of the Ten Commandments, nor of the sign of the Old Covenant, the Sabbath. The Ten Commandments was the law of sin and death, the ministry of death. The New Covenant that started on the Day of Pentecost that held the teachings of Jesus was the ministry of the Spirit. Huge difference. The Spirit is New Wine.
