How do we know that forgiveness is available through Christ?

The assurance of forgiveness through Christ is rooted deeply in Scripture, particularly in the New Testament. Jesus Himself declared that His blood establishes the new covenant, which is a promise of redemption and forgiveness for all who believe (Luke 22:20). The epistles affirm this truth, emphasizing that Christ's sacrifice was sufficient to bear the sins of many, as seen in Hebrews 9:28 and 1 John 2:2. Furthermore, the Old Testament also points towards this reality, where symbols and sacrifices foreshadowed Christ's ultimate sacrifice. Therefore, believers can confidently claim their forgiveness through faith in Christ, who is described as both our atoning sacrifice and our intermediary before God, fulfilling all divine justice and grace.
