There is a clear warning to those who continue down path of the progression of fools
A worthless person, a wicked man,
Is the one who walks with a perverse mouth,
13 Who winks with his eyes, who signals with his feet,
Who points with his fingers;
14 Who with perversity in his heart continually devises evil,
Who spreads strife.
15 Therefore his calamity will come suddenly;
Instantly he will be broken and there will be no healing.
Proverbs 29:1 explains that this sudden calamity does not just happen at the first “mistake” the person made, but actually comes after the wicked person has repeatedly rejected God’s warnings to change his ways.
29 A man who hardens his neck after much reproof
Will suddenly be broken beyond remedy.
One example of God’s gracious patience in giving many reproofs and even final “notice” was King Nebuchadnezzar of Babylon in Daniel 4. God gave Nebuchadnezzar a dream with a warning to change his ways. Then God gave him an entire year to repent and change, but Nebuchadnezzar did not. After the year God lowered the boom and took decisive action to humble him.
One implication of this for those suffering at the hands of narcissists and fools is that while in our weariness of dealing with it we want it FIXED NOW, God also is gracious and patient with them while at the same time providing grace to us. But, He will ultimately deal with them.
