What is the Definition of Immorality?

Immorality Harms


Our culture hazes the truth and devalues absolutes. Many people believe that, if an act doesn’t harm others, then it cannot be immoral. Christian leaders Tim Keller, Collin Hansen, and Al Mohler sit down to define immorality from a biblical perspective and to correct the false view that immorality does not harm.

Timothy Keller is the founding pastor of Redeemer Presbyterian Church in Manhattan and bestselling author of The Reason for God and The Prodigal God. Collin Hansen is an author and serves as editorial director for The Gospel Coalition. Dr. R. Albert Mohler Jr. serves as president of The Southern Baptist Theological Seminary. 




 Some describe immorality as only that which harms someone else. Tim, Collin, and Al point out that immorality hurts the immoral person, community, and society.
