Hello Presidente,
Yes, the great tribulation saints will be exposed to God's wrath, as is demonstrated in the following scriptures:
"Then one of the elders asked me, “These in white robes—who are they, and where did they come from?”I answered, “Sir, you know.” And he said, “These are they who have come out of the great tribulation; they have washed their robes and made them white in the blood of the Lamb.Therefore, they are before the throne of God and serve him day and night in his temple; and he who sits on the throne will shelter them with his presence. ‘Never again will they hunger; never again will they thirst. The sun will not beat down on them, nor any scorching heat. For the Lamb at the center of the throne will be their shepherd; he will lead them to springs of living water.’ ‘And God will wipe away every tear from their eyes.’ ”
* Never again will they hunger
Famine:
"And when He opened the third seal, I heard the third living creature saying, "Come!" And I looked, and behold, a black horse, and the one sitting on it having a pair of scales in his hand. And I heard something like a voice in the midst of the four living creatures, saying, "A choenix of wheat for a denarius, and three choenixes of barley for a denarius; and you should not injure the oil and the wine."
* never again will they thirst (Contaminated Water and water turned to blood towards the end):
"And the third angel sounded his trumpet, and a great star fell out of heaven, burning like a torch. And it fell upon a third of the rivers, and upon the springs of waters. And the name the star is called Wormwood. And a third of the waters became wormwood, and many of the men died from the waters, because they were made bitter.
"And the third poured out his bowl into the rivers and the springs of the waters, and they became blood."
* The sun will not beat down on them, nor any scorching heat.
"The fourth angel poured out his bowl on the sun, and the sun was allowed to scorch people with fire.They were seared by the intense heat and they cursed the name of God, who had control over these plagues, but they refused to repent and glorify him.
The above scriptures demonstrate that, because they are on the earth during the time of God's wrath, the great tribulation saints will have been exposed to God's wrath regarding hunger, thirst and being scorched by the sun as referred to in Rev.7:16.
