Answer: Quite simply, intercessory prayer is the act of praying on behalf of others. The role of mediator in prayer was prevalent in the Old Testament, in the cases of Abraham, Moses, David, Samuel, Hezekiah, Elijah, Jeremiah, Ezekiel, and Daniel. Christ is pictured in the New Testament as the ultimate intercessor, and because of this, all Christian prayer becomes intercession since it is offered to God through and by Christ.
