The bible tells us why he spoke in parables...
Mat 13:10 And the disciples came, and said unto him, Why speakest thou unto them in parables?
Mat 13:11 He answered and said unto them, Because it is given unto you to know the mysteries of the kingdom of heaven, but to them it is not given.
Mat 13:12 For whosoever hath, to him shall be given, and he shall have more abundance: but whosoever hath not, from him shall be taken away even that he hath.
Mat 13:13 Therefore speak I to them in parables: because they seeing see not; and hearing they hear not, neither do they understand.
Mat 13:14 And in them is fulfilled the prophecy of Esaias, which saith, By hearing ye shall hear, and shall not understand; and seeing ye shall see, and shall not perceive:
Mat 13:15 For this people's heart is waxed gross, and their ears are dull of hearing, and their eyes they have closed; lest at any time they should see with their eyes, and hear with their ears, and should understand with their heart, and should be converted, and I should heal them.
but in His infinite wisdom, He chose to speak in ways that we have to interpret.
Not so much...Jesus explained many of the parables...The solution is not interpretation but belief...We must believe the scriptures and then compare them with other scriptures to get the full picture...
Iscool, I’m pretty conversant with the Bible and have spent a lot of time learning and pondering.
The verses that you quote do not answer “why”, other than that it is not for us to know, for now. Still some big “whys” there. Maybe you have figured out the mysteries of the universe, and, if so, good for you and we can quit discussing religion at all.
(Be careful how you answer - I could start quoting Job).
