If it were your intent to provide this explanation, why didn't you just do so in your OP? As it is, this makes it look like your OP was a pretext.
What do you think .I think what was offered was spot on. Or do we seek after the literal and ignore the spiritual understanding hid in that parable ?
You keep forgetting one of the laws of interpretation. Without parables, as prophecy. Christ the anointing teacher . God's Holy Spirit, the Spirit of Christ spoke not.
AS IT WERE". or LIKE UNTO". is used to denote a parable is in view, "
The account is in respect to the first part of the three part demonstration (heart of the earth or belly of the whale, same thing. ).
Part one.. .the garden of Gethsemane demonstration . It is used like the garden of Eden garden. From without messengers with flaming swords guarding the Way the Truth the life. The demonstration of
two propmised in Isiah 53 . Not three four or more.
The Son of man. Jesus and the father alone sufferings and strengthening each other in mutual submission to bring the peace of God that surpasses our understanding. Richly giving us His understanding that works in us .
The work had begun with the two . The father striking the Son of man, Jesus . Jesus crying out and after three times finishing the promise of three (the end of a matter) Then the flaming sword that put the disciple asleep guarding the work of two could be finished . The disciples were not allowed to perform the
work of praying to help strengthen Jesus .
Again that portion of the three part demonstration ( belly of the whale or heart of the earth). It was over and they moved to the second part .(the bloody demonstration the cross ) . A sign to the rebellious world.
Some of the faithless disciples crucified Christ over in over every time they sinned . . exposing Him to public shame as if one demonstration was not enough to the rebellious world .
When suffering unto death, sweat was used to indicate the sufferings the father inflected of the Son of man (the cup of wrath) . Blood like water, both metaphors are used in many parables to represent the pouring of the the Spirit or power. . . attributed to the father.
Literal blood without the spirit has no life to offer .It must be poured out so it can return to the clay of the field .
Spit is used the same way in another parable. Things with DNA (the temporal dying) would seem are used in parables like that.
He has freely given us the valuable tools necessary to unlock the mysteries of faith found in the parables.
2 Corinthians 4:18 While we look not at the things which are seen, but at the things which are not seen: for the things which are seen are temporal; but the things which are not seen are eternal.
Without parables Christ spoke not.
.
Not the cross the second part . Then literal blood was needed to show a literal view to the world . Believers understood the demonstration was that of the lamb of God slain from the foundation .not from the standpoint of the one time demonstration . God is not a man.
