Jesus
always met people where they were.
He used examples of every day occurences as an example if how heavenly things worked( i.e. the sower and the seed )
The great Teacher brought His hearers in contact with nature, that they might listen to the voice which speaks in all created things; and as their hearts became tender and their minds receptive, He helped them to interpret the spiritual teaching of the scenes upon which their eyes rested. The parables, by means of which He loved to teach lessons of truth, show how open His spirit was to the influences of nature, and how He delighted to gather the spiritual teaching from the surroundings of daily life. (CG 51)
The purpose of the parable was to teach. Those that would not listen nor understand, didn't. Those that were truly seeking for wisdom did.
in many hearts the truth had taken no root, and it had been quickly caught away. "Therefore speak I to them in parables." He said; "because they seeing see not; and hearing they hear not, neither do they understand. . . . For this people's heart is waxed gross, and their ears are dull of hearing, and their eyes they have closed." Matt. 13:13-15.
... Christ had truths to present which the people were unprepared to accept or even to understand. For this reason also He taught them in parables. By connecting His teaching with the scenes of life, experience, or nature, He secured their attention and impressed their hearts. Afterward, as they looked upon the objects that illustrated His lessons, they recalled the words of the divine Teacher. To minds that were open to the Holy Spirit, the significance of the Saviour's teaching unfolded more and more. Mysteries grew clear, and that which had been hard to grasp became evident. (COL 20-21)
It served a twofold purpose;
1) It taught a lesson to those in hearing,
2) it hid from them things they weren't yet ready for.
By doing this, as they yeilded more and more to the leading of the Holy Spirit, the lessons became clearer as they watched the every day occurences used to explain heavenly things.
Are they true or false?
I guess it would depend on your personal viewpoint, or, on whether you believe that God cannot lie.
Either they are true, or, Jesus is the biggest liar in history.
Personally, I believe they are true, we just don't understand all there is to understand about them.
