From Genesis to Revelation the Bible is full of godly warnings. Prior to punishing His people, God has always warned them beforehand of His intentions. Tragic occurrences normally come after people have first been warned.

God remains supremely patient and merciful, but for our own long-term good even His patience has limits. When will America's point of no return arrive? When will the dreaded tipping point occur? Let's look at what God has done in the past.
In Noah's time, the Creator gave people 120 years to repent of their utter wickedness (Genesis 6:3And the LORD said, My spirit shall not always strive with man, for that he also is flesh: yet his days shall be an hundred and twenty years.
See All..., 5-7). Noah was "a preacher of righteousness" (2 Peter 2:5And spared not the old world, but saved Noah the eighth person, a preacher of righteousness, bringing in the flood upon the world of the ungodly;
See All...), and so he must have warned his contemporaries of the calamity to come. Even the progress in building the great ark itself should have served as a stark warning. But with the exception of Noah and his family, that entire generation took no heed and perished in the waters of the great Flood.
Jonah was sent to the Assyrian capital city of Nineveh to warn its inhabitants that it would be overthrown in 40 days because of their sins (Jonah 3:2-4 [2] Arise, go unto Nineveh, that great city, and preach unto it the preaching that I bid thee.
[3] So Jonah arose, and went unto Nineveh, according to the word of the LORD. Now Nineveh was an exceeding great city of three days' journey.
[4] And Jonah began to enter into the city a day's journey, and he cried, and said, Yet forty days, and Nineveh shall be overthrown.
See All...). Remarkably, however, the people repented, so God mercifully relented and spared the city. He expressed His merciful concern to Jonah for the welfare of its more than 120,000 inhabitants (Jonah 4:11And should not I spare Nineveh, that great city, wherein are more than sixscore thousand persons that cannot discern between their right hand and their left hand; and also much cattle?

Our Creator repeatedly sent His prophets to both the northern kingdom of Israel and the southern kingdom of Judah long before eventually sending both nations into national captivity. Jesus Christ warned His own first-century generation of the Roman sacking of Jerusalem that would come in an initial form some 40 years later (Luke 21:20And when ye shall see Jerusalem compassed with armies, then know that the desolation thereof is nigh.
See All...; 23:27-31).
How much time does America have? God remains very patient and merciful even when He sees a whole nation going terribly wrong. Ideally, He wants national repentance (see 2 Peter 3:9The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance.
See All...). He offers this promise: "If My people who are called by My name will humble themselves, and pray and seek My face, and turn from their wicked ways, then I will hear from heaven, and will forgive their sin and heal their land" (2 Chronicles 7:14If my people, which are called by my name, shall humble themselves, and pray, and seek my face, and turn from their wicked ways; then will I hear from heaven, and will forgive their sin, and will heal their land.
See All...).
Although God's mercy endures forever, it sometimes takes a different track. The time can come when it is simply too late.
Late in the history of the kingdom of Judah, our Creator instructed Jeremiah not to pray for the nation's people (Jeremiah 7:16Therefore pray not thou for this people, neither lift up cry nor prayer for them, neither make intercession to me: for I will not hear thee.
See All...; 11:14). He told him that it would be "for their good" (Jeremiah 14:11Then said the LORD unto me, Pray not for this people for their good.
See All...). Only a devastating invasion and national captivity would wake them up to see their sins. They had crossed the line. God's mercy had reached its limits, and He decided to act before they grew even more corrupt and degenerate.
What, then, if America fails to repent and suffers the inevitable devastating consequences? If you're an American, where does that leave you?
Recall that God blessed and miraculously protected the prophet Daniel and his three friends right in the midst of Judah's captivity in Babylon. If you really repent, forsaking your breaking of God's commandments and turning to God with your whole heart, He will look after you as well (Luke 21:34-36 [34] And take heed to yourselves, lest at any time your hearts be overcharged with surfeiting, and drunkenness, and cares of this life, and so that day come upon you unawares.
[35] For as a snare shall it come on all them that dwell on the face of the whole earth.
[36] Watch ye therefore, and pray always, that ye may be accounted worthy to escape all these things that shall come to pass, and to stand before the Son of man.
See All...).
That means fighting against human nature, for we are great procrastinators. We put off until tomorrow even the most basic of our spiritual necessities. But God clearly warns us: "Seek the Lord while He may be found, call upon Him while He is near. Let the wicked forsake his way, and the unrighteous man his thoughts; let him return unto the Lord, and He will have mercy on him; and to our God, for He will abundantly pardon" (Isaiah 55:6-7 [6] Seek ye the LORD while he may be found, call ye upon him while he is near:
[7] Let the wicked forsake his way, and the unrighteous man his thoughts: and let him return unto the LORD, and he will have mercy upon him; and to our God, for he will abundantly pardon.

Throughout Genesis the word “days” is use to tell how long someones life would last. I assume that God has not changed what it means in this one verse (Gen 6:3). If that is the case then He is changing mankind's maximum life span to 120 years instead of the almost 1,000 years man had been living, maybe God was getting tired of man striving with Him. Put this 120 years with Matthew 24:34 and we have a prophecy that The Messiah will come within 120 years of Israel becoming a nation, but that time will be shortened. So when the Fig tree (Israel) begins to blossom (the year 1948) we know that we have one generation of mankind, 120 years at the most until the second coming occurs. (1948 + 120 = 2068.) Jesus used a Hebrew idiom for Rosh HaShanah when He said: “of that day and hour knoweth no man, only the Father”. In the first century no one knew when the nation of Israel would be reformed. But it could be that Jesus was saying He woould return on Rosh HaShanah.
In his book “the Harbinger”, Jonathan Cahn explains that the destruction of the Twin Towers was a fulfillment of Shemitah (De 15:1-2) the release of debts, which occurs two days prior to Rosh HaShanah every seventh year. There were 2 or 3 failed attempts on the twin towers that could have been warnings from God. Then 9/11/2001 occurred 2 days prior to Rosh HaShanah, and Freddy Mac and Fannie Mae were rescued 2 days prior to Rosh HaShanah seven years later. Lehman Brothers was not rescued so they went bankrupt. This was a release of their debts. These are all financial institutions. The next Shemitiah occurs 2 days prior to Rosh HaShanah in 2015.
In his 1825AD commentary on Daniel 7:25 Adam Clark mentions the year 2015 in connection to the end being probably not very distant.
I am not a prophet. I don't know how long we have. As a watchman, I am required to warn others when I see some thing coming. This is your warning, repent and be prepared for Shemitah in 2015. You can search the internet for more details.
"When will America's point of no return arrive?"
It arrived circa 720 BC when America's ancestors along with the rest of the northern tribes were carried into exile by the Assyrians. For God said to them at that time:
"Now when she had weaned Lo-Ruhamah, she conceived and bore a son. Then God said: Call his name Lo-Ammi, for YOU ARE NOT MY PEOPLE, AND I WILL NOT BE YOUR GOD." (Hosea 1:9--see also Jer. 3:8)
And America will remain in this "Lo Ammi" condition until after Christ returns. For verse 10 continues:
"Yet the number of the children of Israel shall be as the sand of the sea, which cannot be measured or numbered. And it shall come to pass in the place [land of the Northern Kingdom] where it was said to them, you are not My people, there it shall be said to them, you are sons of the living God. [Rom. 11:7-10, 25, 32]
Furthermore, 2 Chron. 7:14--quoted in the article--applies to God's people prior to His totally (albeit temporarily) disowning them. America in no way is a people called by God's name.
