Sadly, I was unable, either during or after, to view the Ken Ham “State of the Nation 2” speech. However, I’m sure this article probably sums what he covered:
While we would probably all agree that the US was never really a “Christian nation”, it is mostly willful ignorance to discard the fact that our founding fathers started this nation with certain Christian ideals they desired to put into place.
God often blesses nations and individuals to the extent in which they follow His laws. That is especially true for the descendants of Abraham. God often also allows trials and tribulations upon nations and individuals to the extent in which they ignore His laws. That also is especially true for the descendants of Abraham.
Whatever morality this nation may have once had and was founded upon has definitely been thrown out the window. Even the mention of God becomes more and more restricted in public speech every day. There are prophecies throughout the Bible for Israel depicting their fate if they turn their backs upon God. Frankly, even if you do not believe in British Israelism, you should take heed to those prophecies as they should also apply to nations that once claimed to be “under God” but then reject Him.
