Hey Calvin,
You are right about me not putting any confidence in eisegesis, I'm a firm believer in, "My thoughts are not your thoughts," however I
will throw a monkey wrench in what you think about Ismael, Ge 22:2,12,16, ...God did not recognize him to be a son of Abraham because he was a product of Abe's flesh, ...kinda like eisegesis, don't ya think. But lets dig deeper,
And your offspring shall possess the gate of his enemies,
the Ismaelits
want to own the land given to Abraham's descends, that's the cause of all the turmoil in the Middle East today, isn't it, but Scripture teaches they never will,
by your offspring shall all the nations of the earth be blessed, because you have obeyed my voice.
The descendents of Ismael blessing the world? Don't you think if the truth be told, the majority, if not all of the population of the world today, wish the Ismaelits would disappear, and Abraham didn't obey God, God told him not to go to Egypt.
Next..., bro you are not rightly dividing the Word,
In Luke 14 you can't stop at vs 24 because Jesus explains the signification of the parable in vs 26, 27 and He is talking about becoming one of His disciples, ...it's not that the "invitees" weren't prepared, but rather they gave stupid excuses, who would buy land sight unseen, or a team of oxen without first trying them, or get married on the spur of the moment?
Matt 24:15, this is a perfect example of and teaches about people using the name of "Jesus" that aren't His children, they talk the talk and there are lots of them today, but aren't really His. The lady was a Canaanite, but she had
heard the "correct" terminology (Christianese, talk the talk), she thought she could use it too and it would work for her, hence Jesus showing her she wasn't a Jew, however when in humility she stopped the pretense and humbly addressed Him as Lord, approached Him correctly, He heard her, commended her and granted her petition.
Luke 4:18, 19 is where Jesus, at the beginning of His ministry, presented Himself as the Christ to the Jewish nation.
So bro, I can't see where you can reliably exegete the verses you used to arrive at the conclusions you have stated, but I will agree with you there is only one real banquet, not hypothetical and it's the marriage Supper of the Lamb, Rev chapters 4 &5.
show that the Gentile Christians are to augment Israel.
Grafting, the example Paul is using, doesn't augment in this sense, the graft is different from the root stock which is disease resistant but doesn't produce fruit, hence the need to graft to it, and in grafting the root stock doesn't produce fruit, only the branch grafted in produces fruit which agrees completely with Jesus cursing the olive tree and stating the Jewish system of the Law will never produce any fruit again, ...hence the need for a new dispensation, the dispensation of Grace that Paul teaches in Eph 3:2, so let's put the tree together, the Gospel was first preached to the Jews, the root stock, that tree stopped producing fruit so it was cut off below the first branch and the Church was grafted in to preach the Gospel and produce fruit, after the rapture of the Church the final 7 years of Daniel's prophecy has to be fulfilled and Israel will recognize Jesus as their Messiah (remember the 144,000 Jewish Evangelists), that fruitful part of Judaism will be grafted on to the tree above the Church graft and the whole tree makes up the people of the Kingdom of God, Old Testament Saints, Church Saints and Tribulation Saints, they will be the people of the Kingdom when Jesus come to claim His throne on earth, ...keep in mind the Kingdom is inside of us and not visible to the world today.
Now I don't claim to fully understand this and I don't think we will until we are there, but you have started too soon in Rev 21, you/we need to start reading in vs 9, what did the angel
show John, ...it states is was the Bride, but now she is called His Wife, then
what did John see, New Jerusalem.
Look at the foundation first before the doors, it's the Apostles, the city is built on them, i.e. the Gospel and then on the doors are the names of the 12 tribes, kinda looks to me like it's a picture of our grafted olive tree, ...but who can say what the future will be, except God.
Now let's play the what if game, you, me and a couple of Jewish bros come back from cruising the universe, we're thirsty and want a drink, each of the brothers splits off and goes to his respective door, shows his badge and the angel lets them enter, what door are we going to use, ...or do we tunnel through the foundation?
Blessings bro,
Gene
