And with many such parables spake He the word unto them, as they were able to hear it. But without a parable spake He not unto them: and when they were alone, He expounded all things to His disciples. Mark 4:33-34 (KJV)
It has been said, speaking of the parables of Jesus, that, “A parable is an earthly story with a heavenly meaning”. I can see that. It is clear as we read the parables of Jesus that there can be many possible explanations, but Jesus’s understanding is the proper understanding.
The Believer’s Bible Commentary for these verses…
4:33, 34 Verses 33 and 34 introduce us to an important principle in teaching. Jesus taught the people as they were able to hear it. He built upon their previous knowledge, permitting time for them to assimilate one lesson before giving them the next. Conscious of His hearers’ capacity, He did not glut them with more instruction than they could absorb (see also John 16:12; 1 Cor. 3:2; Heb. 5:12). The method of some preachers might make us think Christ had said, “Feed my giraffes” instead of “Feed my sheep”!
Although His general teaching was in parables, He explained them to His disciples in private. He gives light to those who sincerely desire it. BELIEVER’S BIBLE COMMENTARY
Paul the apostle wrote…
But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned. But he that is spiritual judgeth all things, yet he himself is judged of no man. For who hath known the mind of the Lord, that he may instruct him? But we have the mind of Christ. 1 Corinthians 2:14-15
That is part of what Jesus meant when He said in Mark 4:9…
He that has ears to hear, let him hear. (KJV)
When we hear Jesus concerning who He is as our Lord and Savior, our God and Creator we will understand what He teaches.
