I see it more he was talking to mankind the multitude .He is not respecter of corrupted, dying flesh. He informs us to know no man after the flesh as brothers sisters and mothers. All have the same father
Rather than the rebirth of born again Israel (one new birth is required) a new name the father propmised as a beautiful city. . not reckoned of here under the Sun .
He re- named his bride in Acts a more befitting as the bride made up of all nations. Christian . A word with no extra meaning added that literally meanings ."Residents of that heavenly city prepared as His bride the church" She is named after her founder and husband Christ. .

A time like never before or ever again. . . still feeling the effects .
A time when the use of corruptible flesh was cut off .
He spake also this parable; A certain man had a fig tree planted in his vineyard; and he came and sought fruit thereon, and found none. Then said he unto the dresser of his vineyard, Behold, these three years I come seeking fruit on this fig tree, and find none: cut it down; why cumbereth it the ground? And he answering said unto him, Lord, let it alone this year also, till I shall dig about it, and dung it: And if it bear fruit, well: and if not, then after that thou shalt cut it down.Luke 13 6-9
Leaves are used to represent the temporal like flesh. Represented by the veil . When Adam and Eve were revealed as dead they were shown as naked. The glory of God had departed. They used leaves that had no power to make the letter of the law death without effect.. Fig leaves with no fruit are used to represent the healing of nation .Not the fruit of salvation. We walk by faith.
Matthew 21:19 And when he saw a fig tree in the way, he came to it, and found nothing thereon, but leaves only, and said unto it, Let no fruit grow on thee henceforward for ever. And presently the fig tree withered away.And when the disciples saw it, they marvelled, saying, How soon is the fig tree withered away!
1948 is my birth year. Again we walk by faith .The veil is rent.
