It is popular to suggest that everybody knows that they are sinners. But do they really? Scripture teaches us that “every man is clean in his own eyes” and “proclaims his goodness”. Sure most people will concede to doing a few wrong things but grace is never amazing to them because they’ve never contemplated the severe depth of their sin. A give away for this point is that these people often ask the question how can a loving God send people to hell and why is there evil? I’ll allow Voddie Baucham to answer this point.
