How do we know the Atonement is effective for sinners?

The effectiveness of the Atonement can be understood through the manifestation of God's justice alongside His mercy. Romans 3:26 articulates that God is just while also justifying those who believe in Jesus. This dual affirmation emphasizes that true justice, satisfying God's moral law, was achieved through the sacrificial death of Christ. As the ultimate lamb, Jesus took upon Himself not only the sins of humanity but also the weight of divine wrath, satisfying the demands of a holy God.

The Atonement embodies this glorious mystery, where Christ’s suffering and death serve not only as a propitiation for sin but also as a revelation of God’s holiness. Through His sacrifice, the nature of justice is fully displayed, reinforcing the necessity of recognizing both God’s righteousness and the need for a mediator. Hence, it is through Christ that sinners find redemption, as His sacrifice was perfect, sufficient, and divinely ordained to reconcile humankind with God. Those who place their faith in Christ are truly justified, validating the efficacy of the Atonement as fulfilling both the justice and grace of God.
