Featured Jesus is the Savior of All, Especially those that Believe

Let’s break your points down:

1) It is deceitful above all things,

It remains deceitful even after salvation, Let’s see Calvin on Jeremiah 17:

“What is taught here depends on what is gone before; and therefore they ought to be read together. Many lay hold on these words and mutilate them without understanding the design of the Prophet. This is very absurd: for we ought first to see what the prophets had in view, and by what necessity or cause they were led to speak, what was their condition, and then the general doctrine that may be gafilered from their words. If we wist to read the prophets with benefit, we must first consider the reason why a thing is spoken, and then elicit a general doctrine. Thus we shall be able rightly to apply this passage to a common use, if we first understand why the Prophet said, that the heart of man was insidious. He wished, no doubt, to be more earnest with the Jews; for he saw that they had so much wantonness and obstinacy, that a simple and plain doctrine would not have penetrated into their hearts. The declaration, that they are accursed who trust in men, and that no blessedness can be expected except we rely on God, ought to have been sufficient to move them; but when he saw that there was no sufficient power in such a declaration, he added, “I see how it is, the heart is wicked and vicious; so ye think that you have so much craftiness, that ye can with impunity deride God and his ministers: I, says Jehovah, I will inquire and search; for it belongs to me to examine the hearts of men.”

We hence see that there is an implied reproof, when he says, that the heart is insidious and wicked; (175) as though he had said, “Ye think yourselves in this instance wise; is not God also wise?” Isaiah says ironically the same,

“Woe to them who go down to Egypt and make secret covenants, and who trust in horses, as though they could deceive me: ye are wise, I also have a portion of wisdom.” (Isaiah 31:1)

Notice especially the expression, “Ye are wise, etc.;” that is, “Ye are not alone wise; leave to me some portions of wisdom, so that I may be wise like yourselves.” So also in this place, “Ye are deceitful and insidious, and think that I can be deceived:” for astute men are ever pleased with their own counsels, and seek to deceive God with mere trumperies. “Ye are,” he says, “very cunning; but I, Jehovah, will search both your hearts and your reins.” I cannot finish the whole to-day. Deceitful the heart above every thing, And incurable it is,
who can know it?”

Very clear from Calvin in this case “that a simple and plain doctrine would not have penetrated into their hearts” he directed this to the Jewish people and for that matter to all who see themselves as wise, that they don’t need God and they therefore harden their hearts. As we see in Zechariah 7:12 Yea, they made their hearts as an adamant stone, lest they should hear the law, and the words which the Lord of hosts hath sent in his spirit by the former prophets: therefore came a great wrath from the Lord of hosts.

 

2) Beyond cure (and you came to God with a pure heart?)

Paul says we never lose that nature in us to sin, we see that in Romans 17:16-18, in our sarx which is translated flesh (Thayer’s/Strong’s = 3. The sinuous nature), we keep that nature in us for all of our physical life. Again we see Calvin on verse 18.”For I know, etc. He says that no good by nature dwelt in him. Then in me, means the same as though he had said, “So far as it regards myself.” In the first part he indeed arraigns himself as being wholly depraved, for he confesses that no good dwelt in him; and then he subjoins a modification, lest he should slight the grace of God which also dwelt in him, but was no part of his flesh. And here again he confirms the fact, that he did not speak of men in general, but of the faithful, who are divided into two parts — the relics of the flesh, and grace. For why was the modification made, except some part was exempt from depravity, and therefore not flesh? Under the term flesh, he ever includes all that human nature is, everything in man, except the sanctification of the Spirit. In the same manner, by the term spirit, which is commonly opposed to the flesh, he means that part of the soul which the Spirit of God has so re-formed, and purified from corruption, that God’s image shines forth in it. Then both terms, flesh as well as spirit, belong to the soul; but the latter to that part which is renewed, and the former to that which still retains its natural character.”

Here again we have an Old Sinful Nature translated as flesh. Yet we are to come to Christ with a Pure Heart that is a heart which is humble before Him, that is innately in us, that is how everyone must come to Christ, with a humble and contrite heart. Others will harden their hearts and reject God, they are on equal ground with those who believe, they have the same choice to make and yet we are told they hardened their heart.

1 Timothy 4: 2 Speaking lies in hypocrisy; having their conscience seared with a hot iron;

Hebrews 9: : 9 Which was a figure for the time then present, in which were offered both gifts and sacrifices, that could not make him that did the service perfect, as pertaining to the conscience;



Who can understand it? God and God alone.

What caused me and all who come to Christ to have a pure heart that innate conscience built into us by God from the creation. That innate gift of volition from God for all to consciously chose to come to Him with a pure, humble and contrite heart. Those who refuse to come to Him in that way are condemned already because they have refused to belivie on him according to John 3:18, Paul in Romans 10:13 stated Whosoever shall call upon the name of the Lord shall be saved. Believe and Call that is the Godpel and Revelation 22 says the Spirit and the Bride say come, we as believers call the unbeliever to come, but we cannot force them and the Spirit must convict them.

 

Same as it penetrated every believers heart by the conviction of the Holy Spirit as I have already stated!

 

Because I hadn't hardened my heart as some others do.
