It seems like you are the one who cannot tell the difference between literal and exaggeration. Also you cannot accept that hyperbole IS exaggeration.
Yes it will be tedious for you, because, your position is untenable. It takes a lot of flip-flopping to claim "It IS literally true, but, also NOT literally true" simultaneously. And to claim "It IS hyperbole, and it is NOT exaggerated" even though hyperbole IS exaggeration.
There is a massive shift in the rhetoric in the book of John, it is almost like it is a different Jesus. Like I said, compare the Lord's prayer, "give us this day our daily bread, forgive our trespasses... thy will be done on heaven and in earth, amen" with "truly, truly, you can have anything you want as long as you ask in my name". One is proper prayer, the other is magic where "Jesus' name" is a magic word.
The "truly, truly" part is what you keep ignoring. It's not "truly-true" DNB. Are you able to see that?
If you chose to be so hyper-literal, I don't know what to say to you.
Yes, you are correct; 'Truly, truly' is an expression of veracity. But what you don't appreciate is the implied moral requirement on the part of the requestor. I have no idea how else to explain this to you.
God made a covenant with Abram that He will bless him and make him into a great nation - no other stipulations.
But later, we see that there are caveats and further clauses to the agreement - was the first promise an exaggeration?
Initial Covenantal Promise
Genesis 12
1 The LORD had said to Abram, “Go from your country, your people and your father’s household to the land I will show you.
2 “I will make you into a great nation, and I will bless you; I will make your name great, and you will be a blessing.
3 I will bless those who bless you, and whoever curses you I will curse; and all peoples on earth will be blessed through you.”
4 So Abram went, as the LORD had told him; and Lot went with him. Abram was seventy-five years old when he set out from Harran.
Later Iteration
Genesis 17
1 When Abram was ninety-nine years old, the LORD appeared to him and said, “I am God Almighty ;
walk before me faithfully and be blameless.
2 Then I will make my covenant between me and you and will greatly increase your numbers.”
3 Abram fell facedown, and God said to him,
4 “As for me, this is my covenant with you: You will be the father of many nations.
5 No longer will you be called Abram ; your name will be Abraham, for I have made you a father of many nations.
6 I will make you very fruitful; I will make nations of you, and kings will come from you.
7 I will establish my covenant as an everlasting covenant between me and you and your descendants after you for the generations to come, to be your God and the God of your descendants after you.
8 The whole land of Canaan, where you now reside as a foreigner, I will give as an everlasting possession to you and your descendants after you; and I will be their God.”
9 Then God said to Abraham, “As for you, you must keep my covenant, you and your descendants after you for the generations to come.
10 This is my covenant with you and your descendants after you, the covenant you are to keep: Every male among you shall be circumcised.
11 You are to undergo circumcision, and it will be the sign of the covenant between me and you.
12 For the generations to come every male among you who is eight days old must be circumcised, including those born in your household or bought with money from a foreigner—those who are not your offspring.
13 Whether born in your household or bought with your money, they must be circumcised. My covenant in your flesh is to be an everlasting covenant.
14 Any uncircumcised male, who has not been circumcised in the flesh, will be cut off from his people; he has broken my covenant.”
...BTW, verse 14 also alludes to the other discussion that we had on the irrevocable nature of one's nationality - Israel is a theocracy, if you reject or disobey God you will be ostracized from the community.
