How do we know that Christ reversed the curse of sin?

The certainty that Christ reversed the curse of sin rests in the fulfillment of God's redemptive plan. Galatians 3:13 tells us that 'Christ hath redeemed us from the curse of the law, being made a curse for us.' This act of taking our curse upon Himself means that all the wrath due for the elect was borne by Christ, who was made a curse in our place. His resurrection serves as a confirmation that the curse has indeed been broken, securing eternal life for all who believe (1 Corinthians 15:55-57). In His sacrifice, Jesus not only appeased God's wrath but also paved the way for reconciliation, as it is written in 2 Corinthians 5:18, 'All this is from God, who through Christ reconciled us to Himself.'
