Many depend on others for their understanding of parables while some simply ignore them. Matthew 13:34-35 KJV gives reason for you to improve your knowledge in this area: Dating back to the beginning, parables divulges the secrets of God:
All these things spake Jesus unto the multitude in parables; and without a parable spake he not unto them:  That it might be fulfilled which was spoken by the prophet, saying, I will open my mouth in parables; I will utter things which have been kept secret from the foundation of the world.
Teaching in parables, Jesus fulfills the words of the prophet and spiritually, you are brought up to date by the secrets they divulge to you.
Christ involves you in the “Sower”, a parable that you must understand. He wants you to know the role you play as He sows the Word. The parable begins in Mark 4:2-3 KJV:
And he taught them many things by parables, and said unto them in his doctrine,  Hearken; Behold, there went out a sower to sow:
Parables are His Doctrine! Mark 4-8 KJV now gives you the parable of the Sower:
And it came to pass, as he sowed, some fell by the way side, and the fowls of the air came and devoured it up.  And some fell on stony ground, where it had not much earth; and immediately it sprang up, because it had no depth of earth:  But when the sun was up, it was scorched; and because it had no root, it withered away.  And some fell among thorns, and the thorns grew up, and choked it, and it yielded no fruit.  And other fell on good ground, and did yield fruit that sprang up and increased; and brought forth, some thirty, and some sixty, and some an hundred.
Mark 4:13 KJV identifies this as a parable that you must understand:
And he said unto them, Know ye not this parable? and how then will ye know all parables?
Understanding this parable is required, that is, if you want to understand any of His parables. Beginning in Mark 14-15 KJV, Christ gets personally involved:
The sower soweth the word.  And these are they by the way side, where the word is sown; but when they have heard, Satan cometh immediately, and taketh away the word that was sown in their hearts.
Expecting it to root, Christ sows the Word in your heart but when Satan intervenes, it falls by the wayside. Satan then stops it from rooting; he literally prevents you from hearing it. Christ continues to explain the “Sower” in Mark 16-17 KJV:
And these are they likewise which are sown
