I agree we should do as you say but I will not be disappointed if that does not save our country. America has more innocent blood on its hands than all nations that came before us or during our time. We cannot atone for that so I accept whatever punishment God will deliver and that may mean the end of our country.
No, it won't be saved by anyone. The Bible is quite clear God saw this coming from the Garden of Eden. IMO, the die was cast years ago when we took prayer from school. We taught evolution, didn't teach the Bible, and became tolerant of fornication, adultery, abortion, homosexuality, and inventors of all kinds of evil. God knew what would happen when He wrote Leviticus 18:22. Be sure the land will vomit us out soon. America has already fallen.
When the rainbow was projected onto the White House, the counterfeiter used the covenant sign of God to Noah, to show his contempt for what God has made Holy. In Luke 17:28, God added the clincher to prove the reason for the destruction to come. If Sodom had to be overthrown for sodomy, why would America be different? As Noah was saved from God's judgement, Lot also was saved from God's judgement. The land in the valley of Sodom, however, was not! America is for our purposes, finished.
Had the Christians observed 2 Chron 7:14, perhaps God would repent from the action to come, but obviously we haven't. Instead, the other prophesies are being filled as we type. There is a "falling away" of the church, they look for tickled ears and refuse sound doctrine. They have a form of Godliness, but deny the power thereof. The persecution of the church has only now begun and most have no clue what it's like in Syria, or Iraq to be a Christian. Be sure it's coming here. The church will not stand together and the sheep will scatter to become food for the "beasts".
We now have the "Blood Moons" coming spoken of throughout the Bible and the anniversary of Sept 11 is quickly coming. We had another warning Sept of 2008 with the stock market crash.
I hear many Christians saying they will be ruptured out before the persecution starts. Sorry, but we must suffer persecution from man, or the Bible is not true. We are not the children of God's wrath, however, just as Noah and Lot were removed from the wrath from Heaven.
No, America will not be saved and even Israel will be cornered to bring the fullness of the eventual return of Christ.
What are we to do? Live for Christ as each day were your last. Testify of the judgement to come to everyone with ears. Be watchful of the times and seasons so the thief won't wreck your house. Remember that Noah had no idea when the rain would start, but God told Him seven days before the rain started,( Gen 7:4). Lot was given a chance to warn his daughters husbands about the destruction to come. We will know, IMO, if we are watching and listening. 1 Thes 5:4 says we will know if we are sons of the light. All the talk of not knowing the day nor the hour is for others. To a Jew, the day no one knows is The Feast of Trumpets, as it is 2 days. Just as we know "Turkey Day" is Thanksgiving, a Jew knows what day the Trumpets will sound. This year it's on Sept 13, 2 days after Sept 11. The next Blood Moon will be Sept 28, right after the Jubilee year starts. If we make it to Jan 2016, I will be surprised without a major Biblical happening in the world.
