God, being omniscient, knew Hezekiah would humble himself, knew that he would pray, but Hezekiah still had to do it in actuality. This is what we need to see. Not "God changed His mind." Or the other thing that this account is used for---that our prayers change God's mind. And that if they do not, then why pray as has been stated.
I would offer. .
God who humbled Hezekiah like he humbled Jerimiah.
The Holy Spirit working in Jerimiah knew he if he put his words in the mouth of Jerimiah. He knew he would work it out to the pleasure of the father The law of faith . ." let there be my word spoken" and "it was good" (Thou hast well seen: for
I will hasten
my word to
perform it.
Jerimiah 1:4-12 Then the
word of the
Lord came unto
me, saying, Before I formed thee in the belly I knew thee; and before thou camest forth out of the womb I sanctified thee, and I ordained thee a prophet unto the
nations. Then said
I, Ah, Lord God! behold,
I cannot speak: for I am a child.
But the
Lord said unto
me, Say not, I am a child: for thou shalt go to all that I shall send thee, and whatsoever I command thee thou shalt speak. Be not afraid of their faces: for I am with thee to deliver thee, saith the Lord.
Then the
Lord put forth
his hand, and touched
my mouth. And the
Lord said unto
me, Behold, I have put
my words in
thy mouth.
See, I have this day set thee over the nations and over the kingdoms, to root out, and to pull down, and to destroy, and to throw down, to build, and to plant. Moreover the
word of the Lord came unto me, saying, Jeremiah,
what seest thou? And I said, I see a rod of an
almond tree. Then said the Lord unto me,
Thou hast well seen: for
I will hasten
my word to
perform it.
In that way it is God who is of one mind and always does whatsoever his soul desires can make our new hearts soft with the water of His word. he humbled King Josiah in the same way.
