"A lamp on a stand"

I believe you hot the nail on the head brother. As we gain knowledge of the kingdom of God we are equipped with the tools and the power that is needed to glorify God. For unto whomsoever much is given, of him shall be much required and by contrast to whom less is given less is requried.
The Parables of Jesus are for those who have an ear to hear. Not all parables will be fully understood by all. But, I do believe that God will reveal an understanding of most if not all to those who faithfully seek His TRUTH.
STG, I do believe that you are one who digs deep with all your heart for the teachings of our Savior.
May His light be a beacon to shine brightly within your life as you walk His path of obedience and as your reach out to Him for wisdom.

The Purpose of the Parables?

We might think that Jesus spoke in parables to make it easier for people to understand his message. According to the Gospels, however, he surprisingly does NOT expect everyone to understand them! This is clearly expressed in Matthew 13:10-17:
  • 10 Then the disciples came and asked him, "Why do you speak to them [the crowds] in parables?"
    11 He answered, "To you it has been given to know the secrets of the kingdom of heaven, but to them it has not been given.
    12 For to those who have, more will be given, and they will have an abundance; but from those who have nothing, even what they have will be taken away.
    13 The reason I speak to them in parables is that 'seeing they do not perceive, and hearing they do not listen, nor do they understand.' (cf. Isa 6:9-10)
    14 With them indeed is fulfilled the prophecy of Isaiah that says: 'You will indeed listen, but never understand, and you will indeed look, but never perceive.
    15 For this people's heart has grown dull, and their ears are hard of hearing, and they have shut their eyes; so that they might not look with their eyes, and listen with their ears, and understand with their heart and turn-- and I would heal them.'
    16 But blessed are your eyes, for they see, and your ears, for they hear.
    17 Truly I tell you, many prophets and righteous people longed to see what you see, but did not see it, and to hear what you hear, but did not hear it.
In Matthew, at least the disciples of Jesus understand the parables; but in Mark, even they have a hard time understanding, despite receiving extra instructions in private!
