So lets look closely at God's punishment. You mentioned:
Pharaoh's army was wiped out in the Red Sea
Sodom and Gomorrah
Great flood
Drowning is a quick death. As to is being burnt alive. God gave the wicked ample time to repent and only when they were clearly sold out to wickedness, did His '''terrifying'' wrath of a quick death come upon them.
Don't get me wrong, it is terrifying to die. But it would more terrifying to be handed over to someone like Nero, as opposed to God. Nero is hateful. He would put Christians on pikes and set them on fire to provide light for his banquets. They would burn slowly over a few hours. Pretty much like a brazen bull. IE torture! Nero is not righteous in all his ways. God is! Psalm 145:17.
Greetings brother
You are looking at worldly situations again and judging them in your own knowledge.
In the OT God judged the wicked with water, all three items above show this.
But a time is coming when God will judge with Fire.
In earthly terms one could say fire kills the human as fast as water. In basic terms, water enters the body cutting oxygen supply and the brain switches off the body. Fire acts a similar way, smoke cuts off the oxygen supply to the body and the brain switches off the body. If the fire is an intense flame, oxygen will be cut off but the brain will switch the body off even quicker.
Isaiah 66:16 (NKJV)
16 For by fire and by His sword The LORD will judge all flesh; And the slain of the LORD shall be many.
1 Corinthians 3:13 (NKJV)
13 each one's work will become clear; for the Day will declare it, because it will be revealed by fire; and the fire will test each one's work, of what sort it is.
Hebrews 10:26-31 (NKJV)
26 For if we sin willfully after we have received the knowledge of the truth, there no longer remains a sacrifice for sins,
27 but a certain fearful expectation of judgment, and fiery indignation which will devour the adversaries.
28 Anyone who has rejected Moses' law dies without mercy on the testimony of two or three witnesses.
29 Of how much worse punishment, do you suppose, will he be thought worthy who has trampled the Son of God underfoot, counted the blood of the covenant by which he was sanctified a common thing, and insulted the Spirit of grace?
30 For we know Him who said,
"Vengeance is Mine, I will repay," says the Lord. And again,
"The LORD will judge His people."
31 It is a fearful thing to fall into the hands of the living God.
2 Peter 3:10 (NKJV)
10 But the day of the Lord will come as a thief in the night, in which the heavens will pass away with a great noise, and the elements will melt with fervent heat; both the earth and the works that are in it will be burned up.
God has given His Word, ahead of time, He doesn't want any to be lost, but the hard hearted, wicked, sinful, will pay the price for their sin, and it will be by fire. Scripture has a lot to say about fire, but the fire after judgement is very clear.
Matthew 25:44-46 (NKJV)
44 Then they also will answer Him, saying, 'Lord, when did we see You hungry or thirsty or a stranger or naked or sick or in prison, and did not minister to You?'
45 Then He will answer them, saying, 'Assuredly, I say to you, inasmuch as you did not do
it to one of the least of these, you did not do
it to Me.'
46 And these will go away into everlasting punishment, but the righteous into eternal life."
The fire will be 'everlasting punishment' for the wicked, but the righteous, those who have accepted Jesus and practiced righteous will go into eternal life, on the new earth, with the New Jerusalem, the Holy City, with our Lord who will be the light 24 hours a day.
For the wicked eternal punishment, by fire, the saved to eternal life, in the light, with Jesus the Light of the World, the Light in the Holy City, the New Jerusalem.
We all have a choice, we are all given time, until our last breath on earth, we have no one to blame but ourselves.
Look at things from The Word brother, not from worldly comparisons. Why did God give us His Word? So we know the Truth, we will understand His Will for mankind, He has lovingly allowed for those adopted into His family, and even warned those who are saved who continue in repetitive sin. But He has also lovingly said, I do not want any to be lost, I want all to be Saved, my Son died for the sins of All, He paid the price for your sins, so you don't have to. But due to the increase in wickedness in the world He had no option but confirm what must happen to the wicked, the sinners, the lost souls, who reject the Free Gift of Salvation.
Why does He tells us clearly what He wants us to do in verses like these?
Proverbs 3:5-6 (NKJV)
5 Trust in the LORD with all your heart, And lean not on your own understanding;
6 In all your ways acknowledge Him, And He shall direct your paths.
Because He loves us and tells us that is exactly what He wants us to do. Don't compare with worldly, fleshy, examples or comparisons.
Trust in the LORD with all your heart, And lean not on your own understanding;
In all your ways acknowledge Him, And He shall direct your paths.
Peace be with you brother.
