In addition to the fact that nothing is impossible with God, one clue that it is possible for narcissists (those with insolent pride) to change is that God warns them to change. Why would He warn them if change is impossible? God warns scoffers / those with insolent pride to give up their scoffing, accept His reproof and allow Him to transform them through His Spirit.
20 Wisdom shouts in the street,
She lifts her voice in the square;
21 At the head of the noisy streets she cries out;
At the entrance of the gates in the city she utters her sayings:
22 “How long, O naive ones, will you love being simple-minded?
And scoffers delight themselves in scoffing
And fools hate knowledge?
23 “Turn to my reproof,
Behold, I will pour out my spirit on you;
I will make my words known to you.
If the narcissist refuses the wisdom that leads to change, it will ultimately result in calamity for him…..
24 “Because I called and you refused,
I stretched out my hand and no one paid attention;
25 And you neglected all my counsel
And did not want my reproof;
26 I will also laugh at your calamity;
I will mock when your dread comes,
27 When your dread comes like a storm
And your calamity comes like a whirlwind,
When distress and anguish come upon you.
……and he will eat the fruit of the choice he is making.
28 “Then they will call on me, but I will not answer;
They will seek me diligently but they will not find me,
29 Because they hated knowledge
And did not choose the fear of the Lord.
30 “They would not accept my counsel,
They spurned all my reproof.
31 “So they shall eat of the fruit of their own way
And be satiated with their own devices.
32 “For the waywardness of the naive will kill them,
And the complacency of fools will destroy them.
33 “But he who listens to me shall live securely
And will be at ease from the dread of evil.”
Scoffers is one of the names the Bible gives to those with insolent pride, which is the Biblical description for narcissists.
In a difficult prophetic passage God warns the Pharisees of Jesus’ day (see here and here) to give up their scoffing / insolent pride / narcissism….
Isaiah 28:14 – Therefore, hear the word of the Lord, O scoffers, Who rule this people who are in Jerusalem, ………...
Isaiah 28:22 – ……..And now do not carry on as scoffers, Or your fetters will be made stronger; For I have heard from the Lord God of hosts Of decisive destruction on all the earth.
