The unrepentant sinner rejects every appeal.
Sinners prove the evil of their hearts by rejecting the gospel no matter how it is presented to them. Plead, beg, yell, talk softly, implore, scare, entice … it doesn’t matter what style you pick.
Here’s the “Preacher from the Philippines” videos below. His style of preaching isn’t to be criticised as “unproductive” because he does a great service by showing what hypocrites unregenerate men are – they will reject the Preacher from the Philippines just as much as they reject the sweetest and softest and kindliest appeal presented to them.
“And others save with fear, pulling them out of the fire; hating even the garment spotted by the flesh.” Jude 1:23
