In the manual for teachers, there's a section called "Does Jesus have a Special Place in Healing". In this section, it actually talks about how Jesus CAN BE involved in healing. ie miracle working. Which ties in nicely with Jesus telling us "You will see miracles through your hands through me."
Essentially it is saying that Jesus has gone all the way to Heaven, and we should be thankful to Him for achieving this for and with us. And also that he has UNLIMITED POWER, and that He is still with us, and that we should turn to Him for help. It also speaks of how you should call upon or pray in his name, ie "In the name of Jesus Christ", in gratitude to Him and God, as part of healing. That by doing so you are calling upon the power of God.
This is why if you are to LITERALLY lay your hands on people and have Jesus perform "miracles through your hands" through Him, it is because He is currently MORE CAPABLE than you are of performing healing, and calling up on Him to do so is how you can perform miracles for others.
Here's some pertinent parts of what it says:
"Even the most advanced of God's teachers will give way to temptation in this world. Would it be fair if their pupils were denied healing because of this?"
"The Bible says, "Ask in the name of Jesus Christ.""
"What does it mean to call on Jesus Christ? What does calling on his name confer? Why is the appeal to him part of healing?"
"We have repeatedly said that one who has perfectly accepted the Atonement for himself can heal the world."
"He has become the risen Son of God. He has overcome death because he has accepted life."
"There is now no limit on his power, because it is the power of God. So has his name become the Name of God, for he no longer sees himself as separate from Him."
"It means that in remembering Jesus you are remembering God."
"his completed learning guarantees your own success."
"Is he still available for help? What did he say about this? Remember his promises, and ask yourself honestly whether it is likely that he will fail to keep them."
"Who transcends the body has transcended limitation. Would the greatest teacher be unavailable to those who follow him?"
"The name of Jesus Christ as such is but a symbol. But it stands for love that is not of this world. It is a symbol that is safely used as a replacement for the many names of all the gods to which you pray."
"It becomes the shining symbol for the Word of God, so close to what it stands for that the little space between the two is lost, the moment that the name is called to mind. Remembering the name of Jesus Christ is to give thanks for all the gifts that God has given you."
"Jesus has led the way. Why would you not be grateful to him?"
"He has remained with you."
"Would you not learn the lesson of salvation through his learning? Why would you choose to start again, when he has made the journey for you?"
"No one on earth can grasp what Heaven is, or what its one Creator really means. Yet we have witnesses. It is to them that wisdom should appeal."
"No one who has become a true and dedicated teacher of God forgets his brothers."
"Then turn to one who laid all limits by, and went beyond the farthest reach of learning. He will take you with him, for he did not go alone."
"Would God leave anyone without a very present help in time of trouble; a savior who can symbolize Himself?"
"Jesus has come to answer yours. In him you find God's Answer. Do you, then, teach with him, for he is with you; he is always here."
