What does the Bible say about Christ's intercessory work?

Christ's intercessory work is fundamental to the understanding of salvation. After His resurrection and ascension, He is seated at the right hand of the Father, signifying that His work of redemption is complete. In this role, He serves as our mediator, advocating for us before God, ensuring that our prayers and our very selves are accepted because of His righteousness. In 1 John 2:1-2, we see that when we sin, we have an advocate with the Father, emphasizing the ongoing nature of this intercession, which is critical for our assurance of salvation.
