Although Satan is ruthless in his attacks, and can use our children to crush our hearts, we do not let anything separate us from the love we have for God.
God even told us to expect such consequences, when there is "abomination" causing desolation within God's land, due to that land's unfaithfulness,
"12 The word of the Lord came to me: 13 “Son of man, if a country sins against me by being unfaithful and I stretch out my hand against it to cut off its food supply and send famine upon it and kill its people and their animals, 14 even if these three men—Noah, Daniel and Job—were in it, they could save only themselves by their righteousness, declares the Sovereign Lord.
15 “Or if I send wild beasts through that country and they leave it childless and it becomes desolate so that no one can pass through it because of the beasts, 16 as surely as I live, declares the Sovereign Lord, even if these three men were in it, they could not save their own sons or daughters. They alone would be saved, but the land would be desolate (Matt.24:15).
17 “Or if I bring a sword against that country and say, ‘Let the sword pass throughout the land,’ and I kill its people and their animals, 18 as surely as I live, declares the Sovereign Lord, even if these three men were in it, they could not save their own sons or daughters. They alone would be saved.
19 “Or if I send a plague into that land and pour out my wrath on it through bloodshed, killing its people and their animals, 20 as surely as I live, declares the Sovereign Lord, even if Noah, Daniel and Job were in it, they could save neither son nor daughter. They would save only themselves by their righteousness.
21 “For this is what the Sovereign Lord says: How much worse will it be when I send against Jerusalem all four of my dreadful judgments—sword and famine and wild beasts and plague—to kill its men and their animals! 22 Yet there will be some survivors—sons and daughters who will be brought out of it. They will come to you, and when you see their conduct and their actions, you will be consoled regarding the disaster I have brought on Jerusalem—every disaster I have brought on it. 23 You will be consoled when you see their conduct and their actions, for you will know that I have done nothing in it without cause, declares the Sovereign Lord."
[The children being spoken of in verses 22 and 23, are not the literal children we speak of, but rather the remnant and seed of the mother covenant. (Eze.6:8,9; 7:16; Jer.44:28; 30:11; Isa.60:1-15; Rev.21:24-27)].
Yes....when "all four" are sent at once; Could faithful men deliver their own children? No. God would allow the devastation to cause a separation, between those who possess loyal righteousness, from those who do not. There would be no provision for a righteous one to save an unrighteous one, even if it were their own child. This is the nature of the final harvesting (separating) at the end of the age.
We know from Rev.6:8 that God is indeed bringing the "four" (wild beasts, sword, famine and plague) all at once upon His Land. We know why, as the false prophet demands all God's Nation to commit idolatry, under threat of death (Rev.13:15,8,7) (Eze.5:17; 14:15; Lev.26:21,22; Ezra9:13).
Is there still hope?
Whatever God judges regarding my children, I accept it...just as the God-fearing parents of ancient times accepted it
(Deut.21:18-21) (Micah7:6; Luke12:53) (Deut.28:32,41; Rev.13:10).
Yet we have the example of Job, who, after losing his children to the wicked one, received a restoration of offspring (Job1:8-12,18-19) (Job42:10,13,15-17).
We are also told, that God will wipe away each and every tear that causes us pain (Rev.21:4,5,7),
and so as beloved children, we trust in the Love of God (Isa.65:21-23; 66:22; Jer.31:16-17).
