How do we know that the apathy of mankind is true?

Mankind's apathy is affirmed by the consistent message of Scripture, where God's word warns against the consequences of ignoring Him. Romans 1 paints a vivid picture of human nature, illustrating that people suppress the truth in unrighteousness. Moreover, historical examples such as Noah demonstrate that despite God's warnings, many remain unmoved until it's too late. The pervasive indifference we observe in society today further confirms this biblical teaching, showing how deeply entrenched sin affects our response to the gospel.
