The only thing I agree with you on this is that these questions do not in any way address the base underlying presumptions.

You need to remove the whitewash and look into the crypt.

He is attacking the very foundation of your doctrinal framework, showing that you do not really believe that God's actions are limited to the same actions Jesus performed during His 33 years here. For example, God permitted the fiery serpents to attack and kill the Israelites, but Jesus never did that in the NT. That disproves the idea that "Jesus came to show us what God is like" means "God will not do anything Jesus didn't do in the NT."

Actually, GC 35-37 describes one of several ways Jesus punishes and kills sinners. The first passages posted above describes Jesus employing fire and water to punish and kill sinners. Nature is not self-acting. It cannot burn or drown sinners without Jesus empowering it to act. Jesus does not turn nature lose and let it punish and kill sinners. The second passage posted above describes Jesus using His enemies to punish and kill sinners. They serve as His ordained minsters of wrath.

You agree with me that Jesus did things in the OT He didn't do in the NT (while here in the flesh). Ellen White's comment about Jesus in the NT does not undermine what she wrote about Jesus in the OT. "The Saviour is revealed in the Old Testament as clearly as in the New." {DA 799.2}

But the truth still stands - You agree with me. You believe Jesus punishes sinners by withdrawing His restraining hand and permitting nature, evil men, or evil angels to wreak havoc within the limits He sets and enforces. You have absolutely no problem with Jesus doing it. However, if anyone else did it you would find them guilty of wrongdoing. So, you see, you agree with me that Jesus can do "strange acts" that would be wrong and evil for anyone else to do.

Quoting R. Ainslie (just some obscure author in Joe's Story - A simply version of the Bible book of Job)

God does not hurt
God does not punish
God does not condemn
God does not destroy
at any time
in any place
in any way
for any reason
 
Sin does all of these!

Quoting Paul (a prominent inspired author of the Holy Bible):

1 Cor 1:19 For it is written, I will destroy . . . saith the LORD.

Quote the whole verse MM:
1 Corinthians 1:19 For it is written, I will destroy the wisdom of the wise, and will bring to nothing the understanding of the prudent.

God destroys just as He sent the serpents. God is not the executioner of the sentence against sin, as another inspired writer has penned. Satan is the destroyer, as the same writer has penned. The sinner brings the punishment on himself, as the same inspired writer has penned. Fits what I quoted previously!

While He does not delight in vengeance, He will execute judgment upon the transgressors of His law. He is forced to do this, to preserve the inhabitants of the earth from utter depravity and ruin. In order to save some He must cut off those who have become hardened in sin. {PP 628.1}

It was the mercy of God that thousands should suffer, to prevent the necessity of visiting judgments upon millions. In order to save the many, He must punish the few. Furthermore, as the people had cast off their allegiance to God, they had forfeited the divine protection, and, deprived of their defense, the whole nation was exposed to the power of their enemies. Had not the evil been promptly put away, they would soon have fallen a prey to their numerous and powerful foes. It was necessary for the good of Israel, and also as a lesson to all succeeding generations, that crime should be promptly punished. And it was no less a mercy to the sinners themselves that they should be cut short in their evil course. Had their life been spared, the same spirit that led them to rebel against God would have been manifested in hatred and strife among themselves, and they would eventually have destroyed one another. It was in love to the world, in love to Israel, and even to the transgressors, that crime was punished with swift and terrible severity. {PP 325.3}

This judgment and punisment executed in love and mercy you would credit sin as the source?

Furthermore:

God has given in His word decisive evidence that He will punish the transgressors of His law. Those who flatter themselves that He is too merciful to execute justice upon the sinner, have only to look to the cross of Calvary. {GC 539.3}

Who will punish? Will sin execute justice?
