Many people, if not most, say that they are what they are and cannot change and must be accepted as they are.
These people believe Satan who’s lie they have bought and quoted.
The truth is the opposite in that they/you HAVE to change/be changed from within and there is only one Way to do that.
The parable of the clay and the potter.
Can the clay make itself into the image of its Maker, in accordance with Genesis – let Us make man in Our image? How can man make himself into that which he has never seen, and that which he does not know? He can not, just as the clay cannot shape itself on a potter’s wheel.
If the sounding clay will not give itself willingly; without resistance/stiffness (self-will); to the Maker to shape as He sees fit, what use is it, but to be beaten down, clean water added to soften and remove its stiffness (self-will - waywardness), else it is only fit to be thrown out and down into the mire? If it cannot be/refuses to be reformed it is good for nothing, but to be cast out.
This is a reformatory and if the clay refuses to be washed, softened and reformed it WILL be cast out.
Wisdom 33:13. As the clay is in the potter's hand, to fashion it at his pleasure: so man is in the hand of Him that made him, to render to them as liketh Him best (Jer. 18:6).
Isaiah 29:15 Woe unto them that seek deep to hide their counsel from the "I AM", and their works are in the dark, and they say, Who seeth us? and who knoweth us?
29:16 Surely your turning of things upside down shall be esteemed as the potter's clay: for shall the work say of him that made it, He made me not? or shall the thing framed say of him that framed it, He had no understanding?
45:9 Woe unto him that striveth with his Maker! [Let] the potsherd [strive] with the potsherds of the earth. Shall the clay say to him that fashioneth it, What makest thou? or thy work, He hath no hands?
64:8 But now, O "I AM", Thou [art] our Father; we [are] the clay, and Thou our potter; and we all [are] the work of Thy hand (fashion us as Thou will).
Jeremiah words.18:3 Then I went down to the potter's house, and, behold, he wrought a work on the wheels.
18:4 And the vessel that he made of clay was marred in the hand of the potter: so he made it again another vessel, as seemed good to the potter to make [it].
18:5 Then the Word of the "I AM" came to me, saying,
18:6 O House of Israel, cannot I do with you as this potter? saith the "I AM". Behold, as the clay [is] in the potter's hand, so [are] ye in Mine hand, O House of Israel.
18:7 [At what] instant I shall speak concerning a nation, and concerning a kingdom, to pluck up, and to pull down, and to destroy [it];
18:8 If that nation, against whom I have pronounced, turn from their evil, I will repent of the evil that I thought to do unto them.
18:9 And [at what] instant I shall speak concerning a nation, and concerning a kingdom, to build and to plant [it];
18:10 If it do evil in My sight, that it obey not My voice, then I will repent of the good, wherewith I said I would benefit them.
18:11 Now therefore go to, speak to the men of Judah, and to the inhabitants of Jerusalem, saying, Thus saith the "I AM"; Behold, I frame evil against you, and devise a device against you: return ye now every one from his evil way, and make your ways and your doings good.
18:12 And they said, There is no hope: but we will walk after our own devices, and we will every one do the imagination of his evil heart.
