Nothing you have posted above is biblical. It is based on man made tradition and teachings and not based on the Torah or the prophets. What is biblical is the Word of God...
'Israel' "after the flesh", as a '
nation', is left desolate (
Matthew 23:38;
Luke 13:35), to bear no more fruit ever again (
Matthew 21:19), cursed, withered away (
Mark 11:21), dried up from the roots (
Mark 11:20), "twice dead" (
Jude 1:12), and the axe already laid at their root (
Matthew 3:10;
Luke 3:9), cut down and to be thrown into the fire.
The New [or Everlasting] Covenant is only made with the spiritual “Israel” (Jesus Christ, the "elect" of the Father and his children;
Isaiah 42:1;
Matthew 12:18-20), this “Judah” (
Revelation 5:5) and His “house” (
2 Corinthians 1:20 KJB - For all the promises of God in him are yea, and in him Amen, unto the glory of God by us.; – for Christ Jesus, the true “Israel” is the “elect” of God, and thus all who choose to be in Him; see
Isaiah 42:1, 45:4, 65:9 KJB)
ROMANS 9:6-8 [6], FOR THEY ARE NOT ALL ISRAEL WHICH ARE OF ISRAEL,: [7], NEITHER, BECAUSE THEY ARE THE SEED OF ABRAHAM, ARE THEY ALL CHILDREN: but in Isaac shall thy seed be called <Christ> [8], That is, THEY WHICH ARE THE CHILDREN OF THE FLESH, THESE ARE NOT THE CHILDREN OF GOD: BUT THE CHILDREN OF THE PROMISE <those who believe> ARE COUNTED FOR THE SEED.
ROMANS 2:28-29 [28], FOR HE IS NOT A JEW WHICH IS ONE OUTWARDLY; NEITHER IS THAT CIRCUMCISION, WHICH IS OUTWARDS IN THE FLESH: [29], BUT HE IS A JEW WHICH IS ONE INWARDLY; and CIRCUMCISION IS OF THE HEART, IN THE SPIRIT, AND NOT IN THE LETTER; whose praise is not of men, but of God.
Gentile believers are now grafted in by believing and following God's Word *Romans 11:13-27. God's true ISRAEL is everyone who believes and follows God's Word *
John 10:26-27. Your still sitting in the airport waiting for your plane to go on your holiday not knowing that your plane has already departed.
May you receive God's Word and be blessed.
