What does the Bible say about propitiation for our sins?

The term propitiation, found in 1 John 2:2, describes the act of Christ satisfying God's justice through His obedience and sacrifice. It highlights that Christ is not only our substitute and advocate but also the one who appeases God's anger against sin. Importantly, it signifies that God is satisfied with the work of His Son on behalf of His elect, ensuring their salvation. This idea is foundational to understanding grace and the assurance we have in our relationship with God through Christ.
