On the question about what does a wicked heart, deceitful above all mean ? It is well foretold by God, by the following three Apostles of the Lord Jesus Christ, that people will show themselves:
1. Full of unrighteousness, covetousness, full of envy, full of debate, inventers of evil things, without understanding, implacable. ( strong opinion/non correctable.)
2. Men will be covetous, unholy, fierce, heady, high minded. ( will not receive correction. Zephaniah 3:2.)
3. They will speak great swelling words, they will be mockers, they are sensual and have not the Spirit.
4. Envy and strife in the heart, that wisdom descends not from above, but is earthy sensual, devilish. ( where envy and strife is, there is confusion, and every evil work.)
5. False teachers who bring in damnable heresies, many follow their subtle ways, they speak evil of the way of truth.
6. They speak evil of the things they do not understand. ( they have not the Spirit/ no understanding.) they perish in their own corruption, they count it pleasure to riot in the day time, sporting themselves with their own deceiving, while they feast with you, beguiling unstable souls, having a heart that is exercised with covetous practises, they are cursed.
Romans 1:29 Being filled with all unrighteousness, fornication, wickedness, covetousness, maliciousness; full of envy, murder, debate, deceit, malignity; whisperers,
30 Backbiters, haters of God, despiteful, proud, boasters, inventors of evil things, disobedient to parents,
31 Without understanding, covenantbreakers, without natural affection, implacable, unmerciful:
2 Timothy 3:2 For men shall be lovers of their own selves, covetous, boasters, proud, blasphemers, disobedient to parents, unthankful, unholy,
3 Without natural affection, trucebreakers, false accusers, incontinent, fierce, despisers of those that are good,
4 Traitors, heady, highminded, lovers of pleasures more than lovers of God;
Jude 1:16 These are murmurers, complainers, walking after their own lusts; and their mouth speaketh great swelling words, having men's persons in admiration because of advantage.
17 But, beloved, remember ye the words which were spoken before of the apostles of our Lord Jesus Christ;
18 How that they told you there should be mockers in the last time, who should walk after their own ungodly lusts.
19 These be they who separate themselves, sensual, having not the Spirit.
James 3:14 But if ye have bitter envying and strife in your hearts, glory not, and lie not against the truth.
15 This wisdom descendeth not from above, but is earthly, sensual, devilish.
16 For where envying and strife is, there is confusion and every evil work.
2 Peter 2:1 But there were false prophets also among the people, even as there shall be false teachers among you, who privily shall bring in damnable heresies, even denying the Lord that bought them, and bring upon themselves swift destruction.
2 And many shall follow their pernicious ways; by reason of whom the way of truth shall be evil spoken of.
2 Peter 2:12 But these, as natural brute beasts, made to be taken and destroyed, speak evil of the things that they understand not; and shall utterly perish in their own corruption;
13 And shall receive the reward of unrighteousness, as they that count it pleasure to riot in the day time. Spots they are and blemishes, sporting themselves with their own deceivings while they feast with you;
14 Having eyes full of adultery, and that cannot cease from sin; beguiling unstable souls: an heart they have exercised with covetous practices; cursed children:
So, does it mean the heart is deceitful and wicked above all, is to believe those in debate/strife/ those who show they exercise their hearts with covetous practises, or this means that what is told above, is fulfilled in all the heretical threads that have appeared on forums in this end of the world., and it cannot be more apparent, this is fulfilled in every word and every lack of acceptance to the peaceful learning that is from above, which is easy to be entreated. ( James 3:17.)
If the debate goes on, ( which those who have exercised their hearts with covetous practises clearly will do.) it has answered why hearts are wicked and deceitful above all, the heart that never receives correction. ( Sensual, constantly in strife, showing no understanding in those ways, by not having not the Spirit, which is the heart is purified by faith,.)
