How do we know substitutionary atonement is true?

The truth of substitutionary atonement is established primarily through the teachings of Scripture, particularly in key passages like 2 Corinthians 5:21 and Galatians 3:13. These verses articulate the inherent theological framework that God, in His justice, must punish sin, and, in His love, provided a substitute in the person of Christ. This duality provides a foundation for understanding not only the nature of sin but also the magnificent grace offered through the cross.

Historically, theologians have upheld this doctrine as central to the faith, asserting that to deny it is to undermine the very essence of the gospel. The transformative impact of this truth in the lives of believers further affirms its validity—countless individuals testify to the life-changing power of embracing Christ's substitutionary sacrifice. Understanding this doctrine is paramount, as it is through acknowledging our guilt and Christ's redemptive work that we come to experience true reconciliation and peace with God.
