Books of the Saviour: The Advanced Teachings of Jesus Christ

Matthew 13:10 confirms the separate teachings:

The disciples came to Jesus and asked, “Why do you speak to the people in parables?”

He replied, “The knowledge of the secrets of the kingdom of heaven has been given to you, but not to them.

For this people’s heart has become calloused; they hardly hear with their ears, and they have closed their eyes. Otherwise they might see with their eyes, hear with their ears, understand with their hearts and turn, and I would heal them.

This is why I speak to them in parables:

Though seeing, they do not see; though hearing, they do not hear or understand.

In them is fulfilled the prophecy of Isaiah: “ ‘You will be ever hearing but never understanding; you will be ever seeing but never perceiving.’ ”

But blessed are your eyes because they see, and your ears because they hear.

For 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. "

– Matthew 13:10-16

It is not only important to fully understand all of the knowledge within Jesus' teachings, the level within the heavens you will inherit, after your life, depends upon it.
