Blows my mind:
And I say unto you, that many shall come from the east and the west, and shall sit down with Abraham, and Isaac, and Jacob, in the kingdom of heaven: but the sons of the kingdom shall be cast forth into the outer darkness: there shall be the weeping and the gnashing of teeth. Mt 8:11-12
First let's quote the entire context to see what Jesus is talking about:
Mat 8:8 The centurion answered and said, Lord, I am not worthy that thou shouldest come under my roof: but speak the word only, and my servant shall be healed.
Mat 8:9 For I am a man under authority, having soldiers under me: and I say to this man, Go, and he goeth; and to another, Come, and he cometh; and to my servant, Do this, and he doeth it.
Mat 8:10 When Jesus heard it, he marvelled, and said to them that followed, Verily I say unto you, I have not found so great faith, no, not in Israel.
Mat 8:11 And I say unto you, That many shall come from the east and west, and shall sit down with Abraham, and Isaac, and Jacob, in the kingdom of heaven.
Mat 8:12 But the children of the kingdom shall be cast out into outer darkness: there shall be weeping and gnashing of teeth.
Mat 8:13 And Jesus said unto the centurion, Go thy way; and as thou hast believed, so be it done unto thee. And his servant was healed in the selfsame hour.
A centurion had come to him. He had asked healing for his son. He demonstrated "great faith," in that he didn't even ask Jesus to come to his house but believed that He could heal him from afar, right where he was. Thus the exclamation of Jesus in verse 10:
Mat 8:10 When Jesus heard it, he marvelled, and said to them that followed, Verily I say unto you, I have not found so great faith, no, not in Israel.
--Jesus is contrastng the faith of a Gentile, a Roman centuion, to the lack of faith in the nation of Israel.
Then he continues:
Mat 8:11 And I say unto you, That many shall come from the east and west, and shall sit down with Abraham, and Isaac, and Jacob, in the kingdom of heaven.
Mat 8:12 But the children of the kingdom shall be cast out into outer darkness: there shall be weeping and gnashing of teeth.
--The subject is now about the Kingdom, the Millennial Kingdom which the Jews thought that the Messiah, Christ, was bringing. When He didn't, they crucified him. The OT teaches a literal Millennial Kingdom that the Jews are still awaiting for.
Jesus said that many Gentiles, just like this centurion would sit down in this Kingdom with other men of faith such as Abraham and Isaac. Both demonstrated their faith.
He also said that some of these Israelites would never enter the Kingdom. The ones surrounding him hated him. Some of them would be the very ones that would end up crucifying him. The Lake of Fire would await them. They will be cast out into outer darkness; there shall be weeping and gnashing of teeth. There is no evidence of faith with them.
In the Millennial Kingdom only believers will be allowed in. This Roman centurion will be one of those believers.
They say unto him, He will miserably destroy those miserable men, and will let out the vineyard unto other husbandmen, who shall render him the fruits in their seasons. Jesus saith unto them, Did ye never read in the scriptures, The stone which the builders rejected, The same was made the head of the corner; This was from the Lord, And it is marvelous in our eyes? Therefore say I unto you, The kingdom of God shall be taken away from you, and shall be given to a nation bringing forth the fruits thereof. Mt 21:41-43
And what do the last two verses say:
Mat 21:45 And when the chief priests and Pharisees had heard his parables, they perceived that he spake of them.
Mat 21:46 But when they sought to lay hands on him, they feared the multitude, because they took him for a prophet.
He was speaking to those Jews and Pharisees that had rejected him. Remember that not all Jews rejected Christ. He was speaking to those who lived at that time in history. They were God's elect.
When Pentecost came what happened?
Three thousand
Jews got saved.
About 97 thousand
Jews did not get saved! What happened to those thousands of Jews that did not get saved. Did they just disappear into the woodwork. NO, they still exist to this day. They were scattered in 70 A.D. as a judgment, and then they were given their land back and reinstituted as a nation in 1948. They still live as a nation. Christians and Jews live side by side together.
In the OT God called out a nation unto himself--Israel.
Did that mean that all the other nations of the world cease to exist? Under the logic of your system of theology, yes, it does.
But in the NT, God is calling out a nation (not the Jews) unto himself.
Like the other nations in the OT, Israel in the NT still exists, just not presently the "elect of God." She has been set aside for a temporary period of time. There will come a time when God will fulfill his promises to Israel. God is faithful. He does not go back on his promises.
We are not Israel. We have no relationship with Israel.
1Pe 2:9 But ye are a chosen generation, a royal priesthood,
an holy nation, a peculiar people; that ye should shew forth the praises of him who hath called you out of darkness into his marvellous light:
--Israel still exists. But we are a holy nation that God has called out apart from all other nations including Israel.
...if that ain't being replaced then I guess I don't understand the meaning of the word.
That has nothing to do with replacement.
