Deriving truths from a parable

Is hell real? For some who do not believe in hell, the parable of Lord Jesus Christ of Rich man and Lazarus is an imaginary fiction. (Luke 16:19-31) For those wearing jewels is sin, Father providing a Royal welcome to the Prodigal son with a ring is a fable. (Luke 15:11-32)
Master communicator: Lord Jesus used different methods of communication that included teaching, preaching, using poetry, humor, sarcasm, proverbs and spoke many parables. The parables are varied in length, some are in just one verse and others are longer. Some parables are unique in that they are found only in one of the four gospels. One-third of the Lord’s teachings are recorded in parables. It is the most cherished teaching of the Lord Jesus Christ.
False Teaching? If the parables do not convey truth and mislead the hearers, then it becomes false teaching. Those who reject the parables, reject the Lord who is the True Teacher sent by Lord according to Nicodemus. (John 3:2) Lord Jesus is the Truth, His Words are Truth, and it is impossible for Him to lie. (Hebrews 6:18) Hence, deriving truths from a Parable taught by Lord Jesus is right, appropriate, and good for his followers.
Revealed to disciples: The mysteries of the Kingdom of God are revealed to disciples. (Mark 4:10-12) Others who have hardened their hearts due to pride, arrogance, prejudice, self-righteousness, human wisdom, and religious traditions do not understand the truth. They reject the parables as kid’s stuff.
Distinct Advantage: Lord chose parables for the following reasons. First, the abstract principles are made comprehensive to the listeners. Second, parables are more memorable, as they are remembered for a longer time. Third, parables encourage the hearers to think, ponder and discover the truth. Four, parables provide spiritual insights using worldly settings or events.
Allegorical interpretation: However, the Parables of Lord Jesus Christ is not for allegorical interpretation, which could misguide the hearers. For example, in the Good Samaritan parable, giving two coins (denarii) to Innkeeper as the Old Testament and New Testament of the Bible is incorrect. (Luke 10:30-37)
