You are not alone on this observation Brother. This is a basic point that I have brought up many times here. As baptists we are supposed to get our theology from the Bible. Search as I might, I cannot find the reformed covenants of grace, works and redemption in the Bible but I do see the your above mentioned covenants clear as day. How Jehovah could be crystal clear in His covenants to Abraham and obscure with respect to the reformed "covenants" granted to the church is a mystery to me.
Thank you thomas15 for your words of encouragement.
Jeremiah 31:31 Behold, the days come, saith the LORD, that I will make a new covenant with the house of Israel, and with the house of Judah:
Matthew 26:28 For this is my blood of the new testament, which is shed for many for the remission of sins.
I see a promise of a new covenant with Israel.
I see a new covenant ratified by Jesus symbolically at the last supper and with His blood a few hours later.
I see gentiles able to come into salvation.
I do not see gentiles or Jews receiving the full promise of this covenant, yet;
Jeremiah 31:33-34 But this shall be the covenant that I will make with the house of Israel; After those days, saith the LORD, I will put my law in their inward parts, and write it in their hearts; and will be their God, and they shall be my people. And they shall teach no more every man his neighbour, and every man his brother, saying, Know the LORD: for they shall all know me, from the least of them unto the greatest of them, saith the LORD: for I will forgive their iniquity, and I will remember their sin no more.
I do not see a "covenant" with what we call the church. I see Christians who are part of the body of Christ and who have received the forgiveness of sins. I can see a future restoration of Israel and the covenant finalized after this restoration. However, for those of us that are now Christian, we will be with Christ (so we shall ever be with the Lord) and as such will not be recipients of this completed covenant.
Paul talks about an interruption caused by "blindness" that happens to Israel. This is called a mystery and is to last until the full number of gentiles come in. After which Jesus comes and Israel is redeemed and their covenant restored and completed.
Romans 11:25-27 For I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits; that blindness in part is happened to Israel, until the fulness of the Gentiles be come in. And so all Israel shall be saved: as it is written, There shall come out of Sion the Deliverer, and shall turn away ungodliness from Jacob: For this is my covenant unto them, when I shall take away their sins.
The failure of Israel to receive her King and the fulfillment of the new covenant did not hinder gentiles from receiving salvation and the forgiveness of sins.
Ephesians 3:4-6 Whereby, when ye read, ye may understand my knowledge in the mystery of Christ) Which in other ages was not made known unto the sons of men, as it is now revealed unto his holy apostles and prophets by the Spirit; That the Gentiles should be fellowheirs, and of the same body, and partakers of his promise in Christ by the gospel:
The danger in appropriating a covenantal perspective for the gentile church (those who "come in" during the blindness of Israel) is that we risk becoming "wise in our own conceits". We are partakers in the promise in Christ by the gospel. I think we exceed the Bible if we take a view of ourselves that we have replaced Israel or by becoming "spiritual" Jews we have assumed their covenant and promises.
Isaiah 2:2-4 And it shall come to pass in the last days, that the mountain of the LORD'S house shall be established in the top of the mountains, and shall be exalted above the hills; and all nations shall flow unto it. And many people shall go and say, Come ye, and let us go up to the mountain of the LORD, to the house of the God of Jacob; and he will teach us of his ways, and we will walk in his paths: for out of Zion shall go forth the law, and the word of the LORD from Jerusalem. And he shall judge among the nations, and shall rebuke many people: and they shall beat their swords into plowshares, and their spears into pruninghooks: nation shall not lift up sword against nation, neither shall they learn war any more.
I have not seen the mountain of the Lord's house established above all the hills.
I have not seen all nations flowing to it.
I have not seen an end to war.
Revelation 16:18-20 And there were voices, and thunders, and lightnings; and there was a great earthquake, such as was not since men were upon the earth, so mighty an earthquake, and so great. And the great city was divided into three parts, and the cities of the nations fell: and great Babylon came in remembrance before God, to give unto her the cup of the wine of the fierceness of his wrath. And every island fled away, and the mountains were not found.
It may be that the mountains will be leveled such that the one in Jerusalem is the highest.
Gentiles do celebrate the Lord's supper where the declaration of the ratification of the new covenant is remembered. Instead of thinking that this covenant now applies to us, we should instead look forward to the day it will be fulfilled, the remnant of Israel is restored, and goes out of Zion with the law and the word to all nations.
