Has the entire earth already heard the gospel?

[Sister]

So, is anyone denying that the nations have heard the gospel? If so then how will TBN convince people to give so they can REACH EVERY NATION so the Lord can return? Then they use the scripture shamelessly that "First, this gospel must be preached to every nation" they fail to tell the people it happened 2,000 years ago, at least thats my new understanding
