You are correct, there are times when I don’t trust my own feelings because I know very well that they cannot be trusted,
I wish to come back to this as this is central to your very complaint/criticism of mystical practices. I wish to take you into those verses you cite to support your fear and lack of trust of knowing your inner self, as I'm sure you have had some experience where you made poor judgement and suffered for it. However, to go to the extreme of misapplying Bible verses this way to justify cutting oneself off from their entire interiors, their subjective self, is to say the least throwing out the baby with the bathwater. It's more like treating an infected cut on the arm by cutting the arm off, and then justifying that by citing some reference to treating gangrene from the 16th century, which the infection had nothing to do with gangrene in the first place.
To the Bible verses you quoted:
(And you have done worse than your fathers, for behold, each one follows the dictates of his own evil heart, so that no one listens to Me. Jer. 16:12;
"No one listens to me." That's the key. If you cannot trust what is in your heart, how can you trust what you are hearing is God? Let me put this another way, if the heart is deceitful and wicked, then everything you look at and see in the world with be polluted by that. There is no way to claim being objective, because your very thoughts are skewed and will pollute whatever enters into them.
Please understand this. When you say your heart is decietful and wicked, you are incapable of hearing God. You are incapable of reading the Bible and hearing God. You cannot claim "God said this because it's right there on the pages of the book", because you are incapable of hearing what God says. The wicked heart, pollutes whatever it sees. "Having ears to hear they do not hear". Why? The answer is because of this. They are stuck in their own dark imaginations. They are relying on those. And as such, reading the Bible is not going to give you objective truth. You are incapable of seeing anything objectively.
Let me continue...
“The heart is deceitful above all things, And desperately wicked; Who can know it?Jer.17:9
Who can know it? God. Can you know it? Yes. How? By setting aside what you think, by moving beyond how you imagine things to be, and allowing that "still small voice" to speak to your quite, listening mind. Then, and only then, will you be able to see and hear that voice of God. You cannot start from within yourself, read the Bible, and then imagine you "hear" God, and then come here and club people over the head with your supposed "Authority" of the Bible.
So, it appears the only way to heal that poisoned mind, is to go inside yourself. Into the subjective. Without this, everything you see, read, interpret, and understand will be filtered through this "deceitfully wicked" imagination. The mind must be transformed first.
Now you can and will argue that Christ makes that happen when you accept him. But that is magical thinking. It is a process of development to transform the mind. Paul says himself that we should transform ourselves by the renewing of the mind. And it is then and only then that "you will be able to test and approve what God’s will is—his good, pleasing and perfect will" That is a purely subjective enterprise! This is the inner journey. That must take place first.
It is not some magical thing that you can cite and say "That happened when I was saved", and then proceed to walk all over the Bible with your dirty shoes. The mind must be constantly worked on from the inside. And that is not going to happen without going into the depths of the mind into the very soul itself.
...And He said, “What comes out of a man, that defiles a man. For from within, out of the heart of men, proceed evil thoughts, adulteries, fornications, murders, thefts, covetousness, wickedness, deceit, lewdness, an evil eye, blasphemy, pride, foolishness. Mark 7:20-22)
Exactly, and Amen. You need to transform what is inside by looking within and allowing Spirit to cleanse and renew you, to transform you into the "image of Christ". The meditative journey takes you directly into that. You can read books, your can read the Bible until your eyes fall out of your head, but unless you enter within yourself, beyond your ideas of what the truth is, those things you conceive of imagine is true, you will ever and only have just your thoughts. You start there, you end there.
