Today, it's people as individuals that need to fear God. People in leadership are held more accountable, but nations are not being blessed or cursed by God today. In fact, we're told a number of times in Paul's writing that we are going to be persecuted in this world. There are three reasons for our suffering: 1. We suffer for having Christ in our lives, meaning we bear the suffering of Christ; 2. We suffer for the bad decisions we make; 3. We suffer because we live in a fallen world. God allows us to suffer so we can receive the greater glory, but He also helps us in our suffering to be able to bear it. Only Israel in times past had God protect, defend and avenge them. That's not happening today to Israel or to any nation.
I agree He's quite concerned with individuals and their acceptance or not of the Blood covering of His Son as individual's Salvation . . . howsomever . . .
Hati comes to mind. . . voodoo and rampant poverty, corruption . . .
The U.S.A. getting more or less what the masses deserved; did; asked for in Billdo and Shrillery . . . and the resulting worsening of the culture . . .
India, Bangladesh--rampant demonic idol worship correlating with incredible poverty, corruption, abuse.
We shall see before too awfully long the Arab nations disciplined in spite of their blessings of oil.
Nations wherein a majority or even a critical net mass of the population even begins to obey God's principles for living experiences the harvest of blessings from that sowing. Some of the central American countries with a robust Evangelical population growing rapidly have experienced a lot less of the junk El Salvador & Nicaragua have suffered from all the Marxist junk.
I don't know that God is as OVERTLY been cursing and blessing nations. But I suspect He will shortly begin to. I expect to see AUTHENTIC 100% ACCURATE prophetic types on international media stating clearly to nations and leaders what has probably already been told them in private--that unless they mend their ways, increased drought, quakes, etc. will hit by such and such a date--and they will. The Bible notes that God's watchmen in our era will have power to withhold rain. . . or let it loose.
Though I am not sure that I agree that the Bible says this, let me ask: why care about politics? Why care about who gets elected? If it really doesn't matter to God what nations do collectively, then why care whether there are no abortions or 1.2 million per year?
If God created government, and those who serve in it are ministers (Romans 13), why would God have nothing to do with blessing or cursing a nation based on its leadership?
