A power of attorney is a legal instrument; a written authorization, to represent or act on another's behalf in private affairs, business, or some other legal matter. It is a legal document in which the principal designates another person (called the agent) to act on their behalf to make all decisions, in specified matters or all matters. The Bible—God’s legal document, shows Jesus (the principal) authorizing and designating believers (his divinely appointed agents) to cast out devils and heal the sick specifically. Luke 9:1-2 says Jesus “called His twelve disciples together and gave them power and authority over all demons, and to cure diseases. He sent them to preach the kingdom of God and to heal the sick.’”
A power of attorney the disciples exercised here was limited to casting out demons and healing diseases. However, before his crucifixion, Jesus extended the limited authorization to include all matters. In John 16:23, he promised his disciples that in that day [i.e., effective from the day of Pentecost and empowerment by the Holy Spirit], “…whatever you ask the Father in my Name, He will give you.” The Father sent Jesus with unlimited power to save the world, from sin, sickness, and death. (Rom 3:23, 6:23—"…all have sinned and fallen short of the glory of God. For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord”). So, Jesus came authorized by the Father and full of the Holy Spirit; to do the work of the Father (Luk 4:1, Jn 14:10) which included healing diseases, casting out demons, and creating miracles (Jn 5:36; 10:25, 32, & 38).
Jesus planned to designate his disciples with the full and unlimited power of attorney before his crucifixion. So, we can legally represent him and even do more works than he did. He said in John 14:12-16 “Most assuredly, I say to you, he who believes in Me, the works that I do he will also do; and greater works than these he will do, because I go to My Father. And whatever you ask in My name, that I will do, that the Father may be glorified in the Son. If you ask anything in My name, I will do it. …And I will pray the Father, and He will give you another Helper [Holy Spirit] that He may abide with you forever.”
After his resurrection, he designated his disciples as his true agents, with full and unlimited power to truly represent him, as he represented the Father. He said to them “As the Father has sent me, I also send you.” Then he breathed on them, “saying receive the Holy Spirit” (Jn 20:21). The Holy Spirit was poured out on the day of Pentecost to add vitality to the legality of our power of attorney, as true disciples and Christians, to use his name as we desire to save and heal the world in word and power. To this end, Peter commanded a man crippled from birth, to rise and walk, in the name of Jesus Christ, and the man leaped, stood, walked, and praised God (Act 3:6).
From Peter to Philip, to Paul working unusual miracles (Act 8:6, 19:11), to the prayers and miracles that rocked the world during the greatest revivals of the 18th, and 19th centuries, the matchless name of Jesus was the secret power in them. The Name of Jesus had all the answers in the early and middle 20th century, from the unusual miracles and manifestations of power at Azusa Street; to Dr. John Lake’s healings of hundreds of thousands of people in South Africa and Spokane Washington D.C.; to the healing ministries of the Kathryn Kuhlman’s and Oral Roberts, and others. In China, United States, Africa, Europe, and all around the world miracles are happening because we have power of attorney to cast out demons, heal sickness, and create miracles.
Regardless that healings and miracles are happening here and there and somewhere in the world, the amount is still a tip of the iceberg. We must arise and realize that we have power of attorney to heal all manner of sickness and diseases, to do good, and set all free that are oppressed of the devil. Jesus commanded us to “Go into all the world and nations.” To heal them, to preach the kingdom, to baptize them, to make disciples, and to teach them because “All power and authority have been given to him” (Mat 28:19). And he endued us who have believed and are baptized into him, with power from on high by his Holy Spirit, who adds vitality to the legality of divine healing. Will you embrace the responsibility to make everyone healthy in your world—family, community, and city—through divine healing as your power of attorney?
