How do we know that Christ's intercession for us is effective?

The effectiveness of Christ's intercession is grounded in His sacrificial role as our mediator. In the sermon, Abigail's actions represent Christ's role, as she intercedes for Nabal, asking for his sins to be laid upon her. Similarly, Christ, though sinless, took upon Himself the sins of His people (2 Corinthians 5:21) and made atonement through His death. Romans 8:34 reinforces this understanding, stating that Christ intercedes for us at the right hand of God. The true essence of Christian redemption lies in this unblemished exchange—our sins are transferred to Him, and His righteousness is granted to us, ensuring our acceptance before God.
