What is the concept of intercession in the Bible?

In biblical terms, intercession is portrayed as a vital act of mediation, where one person advocates on behalf of another before God. This is beautifully exemplified by Christ, who intercedes for His people based on His atoning sacrifice, as illustrated in Romans 8:34. The act of interceding involves appealing to God's justice and mercy on behalf of those who cannot stand on their own merit. By this, the faithful assure themselves and others of God's favor and mercy, echoing the character of Christ, who bore our sins and intercedes for us as our high priest.
