What does the Bible say about why men hate the gospel?

Men often hate the gospel because it exposes their sinful nature and the futility of their works. The gospel declares that salvation is by grace alone through faith, stripping individuals of their self-confidence and self-righteousness. As Paul stated, the flesh is enmity against God, and those who cling to their works and traditions naturally despise the message of grace. Galatians 4:16 highlights this by emphasizing, 'Am I therefore become your enemy, because I tell you the truth?' When faced with the truth of the gospel, many prefer to cling to their established beliefs and traditions rather than accept the radical grace that God offers through Jesus Christ.
