Course Overview

Sin is humanity’s oldest and deepest problem. It lies at the root of every form of suffering, injustice, and spiritual death. “The Greatest Problem of Mankind” is a fundamental, Scripture-based course that takes you on a journey from the Garden of Eden to the cross of Christ, revealing the full story of how sin entered the world and how God provided the only solution.

Through this course, you will discover what sin truly is - not just wrongdoing, but rebellion against a holy God. You will learn how sin separates us from our Creator, corrupts human nature, and leads to both physical and spiritual death. More importantly, you will come to see the heart of God, who, in His justice, could not ignore sin, yet in His mercy, chose to redeem mankind through His Son. Each lesson will help you understand the seriousness of sin, the beauty of divine forgiveness, and the call to live a transformed life through Jesus Christ.
