Jeremiah 17:9 -- The heart is more deceitful than anything else and desperately sick—who can understand it?

"who can understand it?"  Father can, I am certain.  However, by trying to delve into that area, and to understand what Father understands, is to try to delve into things that belong to Father, and Father should be the one to mold one's heart, not the oneself doing the work.  Again, it would be like understanding all the inner workings of the mind in how it produces a signal to the heart to pump blood.  If a person understood those things, they could potentially kill what Father has created, even by accident.  There are things that are not within people's control for good reason.

So, by this, the keys to remember include that one must never try to invalidate scripture, or that is like trying to stop Father's prophecies.  What understanding Father has provided is for a purpose and can be helpful, and is good and is what Father believes one is ready for.  At the same time, Father is the potter, and we are the clay, so we must submit to how Father molds us, rather than trying to constantly mold ourselves.  This also being that if we follow with Father's love, and Will, all will come together as it should.  And then, there are certain things that are under Father's control for many reasons, of those included are that they are there as protection, they are so Father's Will can produce a perfect paradise, and truly, it is Father's energy.

On a personal note, so that others may not make the same mistakes, I do need to stop trying to understand things and be able to control things and make them into what I think they should be, or to force things in my heart when Father is trying to motivate me in other ways.  It is cowardly to not follow the direction Father is providing in one's heart, which is multifaceted (which not only includes what one feels, but also what one remembers (as emotions can be tied to memories, and help oneself to remember things a lot), what is seen, and many more things that can continually be delved into and further understood), as a coward really only destroys themselves.  Something to keep in mind:

Revelation 21:8 -- "But the cowards, unbelievers, vile, murderers, sexually immoral, sorcerers, idolaters, and all liars—their share will be in the lake that burns with fire and sulfur, which is the second death."

At the same time:

Proverbs 30:18-19 -- Three things are beyond me;
    four I can't understand:
    the way of an eagle in the sky,
    the way of a snake on a rock,
    the way of a ship at sea,
    and the way of a man with a young woman.

To understand what is being said here is more than enough.  To try to reach for them, or try to understand them would be to squelch into Father's territory, which all belongs to Father, and not oneself.  Moreover, to try to go too far would be to try to break Father's Word, and that is a horrible sin to itself.

It is okay to act on certain feelings within one's heart.  It is not okay to transgress willfully against Father.

Something interesting that just came to mind is that a part of being able to follow and adhere to Father's Law is to be able to better remember all of the specific details.  When this is possible, it simply can't be forgotten.

If oneself is full of Father's light, then it is not only their heart, or their eye, but also their mind that is full of Her Truth.  Every part.

It seems that a warning sign in that one has strayed off of Father's path would include a sort of stifling of the Wisdom that comes from Father.  At the same time, a part of having courage and humility towards Father is to take courage in doing things like sleeping on a mattress rather than on the floor.  To have the humility to obey Father even in things that oneself may not think are one thing, but may not actually be.  However, the Truth in all matters, of which one has been gifted with, do not change, and must be adhered to.
