John, we are having a healthy conversation. Iron sharpens iron — Proverbs 27:17.
First, you are correct. The initial number of saints on the day of Pentecost was 120 persons including Christ’s mother Miriam and His brothers. As you know, on the day of Pentecost, after Peter preached Christ, about three thousand souls joined the disciples. On another occasion about five thousand souls joined in one day.
Also, Zechariah 13 prophesied that Christ would carry one third of Israel through the Christian fire. Two thirds were cutoff.
Zechariah 13:6 KJV And one shall say unto him, What are these wounds in thine hands? Then he shall answer, Those with which I was wounded in the house of my friends.
Zechariah13:7 Awake, O sword, against my shepherd, and against the man that is my fellow, saith the LORD of hosts: smite the shepherd, and the sheep shall be scattered: and I will turn mine hand upon the little ones.
Zechariah13:8 And it shall come to pass, that in all the land, saith the LORD, two parts therein shall be cut off and die; but the third shall be left therein.
Zechariah 13:9 And I will bring the third part through the fire, and will refine them as silver is refined, and will try them as gold is tried: they shall call on my name, and I will hear them: I will say, It is my people: and they shall say, The LORD is my God.
Unbelieving Israel did not call upon The Lord Jesus.
Second, you are correct again that the nation of Israel has covenant and unfulfilled promises. Christ is coming back the second time to rescue and save Israel. However, it is also true that all unbelievers with respect to Christ are cutoff. Look at Romans 11.
Romans 11:5 KJV Even so then at this present time also there is a remnant according to the election of grace.
Romans 11:6 And if by grace, then is it no more of works: otherwise grace is no more grace. But if it be of works, then is it no more grace: otherwise work is no more work.
Ro mans11:7 What then? Israel hath not obtained that which he seeketh for; but the election hath obtained it, and the rest were blinded
Romans 11:8 (According as it is written, God hath given them the spirit of slumber, eyes that they should not see, and ears that they should not hear;) unto this day.
Romans 11:9 And David saith, Let their table be made a snare, and a trap, and a stumblingblock, and a recompence unto them:
Romans 11:10 Let their eyes be darkened, that they may not see, and bow down their back alway.
Romans 11:11 I say then, Have they stumbled that they should fall? God forbid: but rather through their fall salvation is come unto the Gentiles, for to provoke them to jealousy.
Romans 11:12 Now if the fall of them be the riches of the world, and the diminishing of them the riches of the Gentiles; how much more their fulness?
Romans 11:13 For I speak to you Gentiles, inasmuch as I am the apostle of the Gentiles, I magnify mine office:
Romans 11:14 If by any means I may provoke to emulation them which are my flesh, and might save some of them.
Romans 11:15 For if the casting away of them be the reconciling of the world, what shall the receiving of them be, but life from the dead?
Romans 11:16 For if the first fruit be holy, the lump is also holy: and if the root be holy, so are the branches.
Romans 11:17 And if some of the branches be broken off, and thou, being a wild olive tree, wert graffed in among them, and with them partakest of the root and fatness of the olive tree;
Romans 11:18 Boast not against the branches. But if thou boast, thou bearest not the root, but the root thee.
Romans 11:19 Thou wilt say then, The branches were broken off, that I might be graffed in.
Romans 11:20 Well; because of unbelief they were broken off, and thou standest by faith. Be not highminded, but fear:
Romans 11:21 For if God spared not the natural branches, take heed lest he also spare not thee.
Romans 11:22 Behold therefore the goodness and severity of God: on them which fell, severity; but toward thee, goodness, if thou continue in his goodness: otherwise thou also shalt be cut off.
Romans 11:23 And they also, if they abide not still in unbelief, shall be graffed in: for God is able to graff them in again.
Romans 11:24 For if thou wert cut out of the olive tree which is wild by nature, and wert graffed contrary to nature into a good olive tree: how much more shall these, which be the natural branches, be graffed into their own olive tree?
Romans 11:25 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.
Romans 11:26 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:
Romans 11:27 For this is my covenant unto them, when I shall take away their sins.
Romans 11:28 As concerning the gospel, they are enemies for your sakes: but as touching the election, they are beloved for the fathers’ sakes.
Romans 11:29 For the gifts and calling of God are without repentance.
Also 1 John 5 KJV says only those that believe in Christ are connected to The Father and have access to eternal life. Unbelievers are lost if they die in unbelief. A hard to accept fact, but a fact nevertheless.
1 John 5:10 He that believeth on the Son of God hath the witness in himself: he that believeth not God hath made him a liar; because he believeth not the record that God gave of his Son.
1 John 5:11 And this is the record, that God hath given to us eternal life, and this life is in his Son.
1 John 5:12 He that hath the Son hath life; and he that hath not the Son of God hath not life.
Christians are in covenant with Christ. So are faithful Christian nations like America once was.
