“I have set watchmen on thy walls, which shall never hold their peace day nor night: ye that are the Lord’s remembrancers, keep not silence, and give Him no rest.”—Isa. lxii. 6. Study these words until your whole soul be filled with the consciousness, I am appointed intercessor. Enter God’s presence in that faith. Study the world’s need with that thought—it is my work to intercede; the Holy Spirit will teach me for what and how. Let it be an abiding consciousness: My great life-work, like Christ’s, is intercession—to pray for believers and those who do not yet know God.
