It seems logical that an expert in a given thing will have at least some knowledge about that given thing.
And yet, you USA, being expert in sin, appear to have no knowledge - at least based on your behavior - as to what sin really is.
Therefore, let's use God's Word, the Bible, to see how it can help.
The Bible defines what sin is in three basic ways:
(1) From James 4:17, if we know to do good and don't do it, it's sin. (Likewise, if we know a thing is wrong but do it anyway, it's sin.)
(2) From 1 John 5:17, all unrighteousness is sin.
(3) From 1 John 3:4, sin in lawlessness (NKJV), or similarly stated in the (KJV), sin is transgression of the Law. What Law ? God's Law, that is, God's Commandments, the same Law specified in James 2:10-11, Romans 7:7, Matthew 5:17-19, and elsewhere in the Bible.
So it's fairly simple. Sin is the breaking of God's Commandments.
Now, if one does not care to know God's Commandments, they will obviously remain ignorant of what sin is, and will almost assuredly be practicing lawlessness; not because they are truly ignorant, but because they are willfully ignorant, knowing that God and Jesus are good, and yet still refusing to know God's Law, even though God ensures that it is available practically anywhere (including here).
So, how will it work out for those who know God and Jesus are good, including those who might even see themselves as "religious" or "spiritual", but who still refuse to know, much less keep, God's readily available Law, and therefore continue practicing lawlessness ?
Let's ask Jesus:
“Not everyone who says to Me, ‘Lord, Lord,’ shall enter the kingdom of heaven, but he who does the will of My Father in heaven. Many will say to Me in that day, ‘Lord, Lord, have we not prophesied in Your name, cast out demons in Your name, and done many wonders in Your name?’ And then I will declare to them, ‘I never knew you; depart from Me, you who practice lawlessness!’" - Matthew 7:21-23
Obviously then, to enter the kingdom of heaven, we must do the will of God in heaven and NOT practice lawlessness.
Jesus is also clear that anyone continuing in willful sin, breaking God's Commandments, no matter what good they might do otherwise, will NOT be going to Heaven.
So USA, the basic problem has nothing to do with any of the good you might do from time to time.
The basic problem is with your continuing in the bad, that is, your persistence in willful sin over what is now many years and decades.
But you say, "We know God !"
So what ? Even the devil knows who God is, and believes that God is, in fact, God.
"Even the demons believe—and tremble!" - James 2:19
Merely knowing who God is, and even knowing His Commandments, does nothing in and of itself.
Without repentance, forgiveness of others, and doing God's Commandments, you'll remain lost, and with further destruction to come.
"Do not be deceived, God is not mocked; for whatever a man sows, that he will also reap." - Galatians 6:7
"For not the hearers of the law are just in the sight of God, but the doers of the law will be justified." - Romans 2:13
"But be doers of the word, and not hearers only, deceiving yourselves." - James 1:22
"But why do you call Me ‘Lord, Lord,’ and not do the things which I say?" - Jesus in Luke 6:46
"My mother and My brothers are these who hear the word of God and do it." - Jesus in Luke 8:21
"If you love Me, keep my commandments." - Jesus in John 14:15 (emphasis added to these Verses)
It's sad, USA, that with all your self-declared wisdom, you still refuse to see.
And because you do not Love God and Jesus or Their Word, you also continue in sin.
In fact, instead of a valuable "city on a hill" (or "indispensable" as your leaders proudly self-proclaim), you have become little but sin.
You are not Christian, no matter how many false claims and empty words you use to pretend otherwise.
In fact, you are anti-Christ, due to the sin you have become, through-and-through.
"What sin ?" you ask.
The sin that you no longer recognize, because it now merely seems like "normal", acceptable behavior to you.
As a fish barely notices the water it swims in, and people barely notice the air they breathe, so you do not notice your own sin.
Both within your nation, as well as outside your nation by your humiliating and terrorizing treatment of other nations around the world, you have not Loved God, nor anyone else as yourself; your sinful actions are the proof: unceasing war, violence, murder, hatred, pride, self-righteousness, disrespect, greed, selfishness, thefts, covetousness, lies, deceit, gossip, slander, self-exaltation, lusts, lewdness, adulteries, perversions, destruction of proper family structures, blasphemies, abuse of God's Name, abuse of God's True Sabbath, immaturity and idolatry of every sort including the worship of money, people, culture, and self; and even destruction of the very Earth.
If you, USA, would bother to open your eyes and hear with your ears, you would understand that even the endless OMGs that spew from your people's mouths are a sin, a marginalizing disrespect of God and vain misuse of His name that breaks Commandment #3.
But you do not care, nor see, nor hear.
"For the hearts of this people have grown dull.
Their ears are hard of hearing,
And their eyes they have closed,
Lest they should see with their eyes and hear with their ears,
Lest they should understand with their hearts and turn,
So that I should heal them."
- Jesus in Matthew 13:15, quoting the Prophet Isaiah, regarding the hard-hearted who refuse God's healing Salvation
And so your sins continue (some of which are discussed here).
The above letter was originally written October 10, 2018.
At that time, it also contained a foreshadowing of a particular USA event which came true on Dec 29, 2018.
That event, which most people no longer recall but which God saw, was a marker along the USA's path toward destruction.
This letter was then edited a year later, on October 10, 2019, to reflect the latest position on that path for the USA.
The former event was removed, and was replaced by this: a final forewarning to the USA that the day of recompense looms close.
Repentance could spare you, USA, but you will not repent.
Therefore, by your own willful choosing and your continued hatred of God, Jesus, and Their Word, it's now just a matter of time.
And you will not be able to pretend you didn't know.
God bears long, but in the coming day of your self-inflicted punishment, He will no longer restrain.
At that time, you will know that the One who wants us to cease sin is also the One whom you should fear.
In Love and Truth,
