Zechariah 12
10 And I will pour upon the house of David, and upon the inhabitants of Jerusalem, the spirit of grace and of supplications: and they shall look upon me whom they have pierced, and they shall mourn for him, as one mourneth for his only son, and shall be in bitterness for him, as one that is in bitterness for his firstborn.
Dispensationally,
None of "Israel who are living at that time" in the future will have pierced Him. But Judas, Caiaphas, and the Jewish rulers are those who pierced Him, and they are those who will be present, and who will look upon Him, and mourn for Him, and repent.
And the spirit of grace and supplications is poured upon the house of David. Is that not the house of David in the era of Judas, Caiaphas, and the Jewish rulers?
And if the house of David from that era is saved, why is not the house of David of all time saved?
Why would the God who loves Israel not save all Israel of all time?
Or are Judas, Caiaphas, the Jewish rulers, and "Israel who are living at that time", the only ones deserving of salvation?
The rebels are purged in Zechariah 13. But they are first saved in Zechariah 12.
Israel is the concept of a Physical agency through which God would operate on this very Physical Earth - a kingdom of Priests.
An agency an Israelite was entered into by Physical circumcusion - which was to be symbolic of his circumcision of his heart (faith towards God), as he began to live out the Shema - and "all this law" by faith, that he was taught and brought up in, as a child.
His being an Israelite did not automatically grant him entry unto that agency relationship with God.
Rather, those God given rituals as a means of both his entry into and of his maintainance of said agency relationship with God by faith, (circumcision of the heart) did.
God loves Israel, the agency.
Which only applies to an Israelite in a right relationship with said agency.
Scripture is repeatedly clear on this.
Acts 7:51 Ye stiffnecked and uncircumcised in heart and ears, ye do always resist the Holy Ghost: as your fathers did, so do ye. 7:52 Which of the prophets have not your fathers persecuted? and they have slain them which shewed before of the coming of the Just One; of whom ye have been now the betrayers and murderers: 7:53 Who have received the law by the disposition of angels, and have not kept it. 7:54 When they heard these things, they were cut to the heart, and they gnashed on him with their teeth.
Romans 2:17 Behold, thou art called a Jew, and restest in the law, and makest thy boast of God, 2:18 And knowest his will, and approvest the things that are more excellent, being instructed out of the law; 2:19 And art confident that thou thyself art a guide of the blind, a light of them which are in darkness, 2:20 An instructor of the foolish, a teacher of babes, which hast the form of knowledge and of the truth in the law. 2:21 Thou therefore which teachest another, teachest thou not thyself? thou that preachest a man should not steal, dost thou steal? 2:22 Thou that sayest a man should not commit adultery, dost thou commit adultery? thou that abhorrest idols, dost thou commit sacrilege? 2:23 Thou that makest thy boast of the law, through breaking the law dishonourest thou God? 2:24 For the name of God is blasphemed among the Gentiles through you, as it is written. 2:25 For circumcision verily profiteth, if thou keep the law: but if thou be a breaker of the law, thy circumcision is made uncircumcision.
2:28 For he is not a Jew, which is one outwardly; neither is that circumcision, which is outward in the flesh: 2:29 But he is a Jew, which is one inwardly; and circumcision is that of the heart, in the spirit, and not in the letter; whose praise is not of men, but of God.
