How do we know Jesus Christ is our propitiation?

Jesus Christ is referred to as the propitiation for our sins in 1 John 2:2, indicating that through His sacrifice, He satisfies the wrath of God against sin. This term signifies that Christ not only acts as an intermediary but also as the means by which we receive forgiveness. The concept of propitiation emphasizes the seriousness of sin and the need for divine justice, showcasing Christ's sacrificial death as the fulfillment of that need. Thus, His role as propitiation underscores the glory of God's grace offered to His elect.
