What does the Bible say about the propitiation of our sins?

In 1 John 2:2, the term 'propitiation' signifies that Jesus is both the sacrifice who appeases God's wrath and the means by which we are reconciled to Him. Jesus’ death on the cross serves as the full payment for our sins. It means that all who come to Him in faith have their sins forgiven and are made right before God. This concept is crucial in Reformed theology, emphasizing that God’s justice is satisfied through Christ's atonement, and thus believers can approach God without fear of condemnation. His sacrifice was not limited but extends to the whole world, as indicated in the same verse, implying the available grace for all who would believe.
