lots of people complain it’s too simple.
if that’s true why is over two-thirds of the world that have heard it, unable to accept it?
it’s hard to accept because it makes absolutely no sense to the natural (unsaved/pre-accepted salvation) man. “the world” does not work this way, which is what he/she knows. nothing is free. certainly nothing valuable is free. you have to do something in return for something valuable. the more valuable, the more you are going to have to do.
this is why it is very hard for the unsaved person to accept the real gospel message.
Spiritual blindness on a massive scale. It does not appeal to prideful people, who actually think they have what it takes to help God along. It goes against the grain for prideful people to admit they are morally bankrupt.
