Letters of Authority When Jesus ascended to heaven, He expressed at least two promises of far-reaching significance: (1) He would build a Church and (2) He would give the Church authority to act in His name. He further made clear that the Holy Spirit’s coming would provide the power to accomplish these tasks. As participants in His building process, we need to understand the authority the Spirit has brought us. “Whatsoever you ask in my name,” Jesus said, “the Father will do it for you.” And, “All authority has been given to Me in heaven and on earth” (Matt. 28:18). These credentials—the privilege of praying and operating in the name of Jesus—are letters of authority pressed into your hand by Christ the King.
