And whatsoever ye shall ask in my name, that will I do, that the Father may be glorified in the Son.(John 14:13)
You have a right to freedom from pain and sickness. In Jesus' Name, you can command them to leave.
Many people are always trying to get someone else to do it for them. Sometimes you can exercise your authority for someone else, and sometimes you can't.
If you could always receive the blessings of God for others, that would relieve them of all responsibility. But the Bible teaches individual responsibility.
You have certain rights in the natural. For example, as a United States citizen, you have the right to vote in elections. I can't vote for you. You must be the one who exercises your rights, not someone else.
That's also true in the spiritual. God the Father has given you authority over demon forces in the Name of Jesus. So you can use that Name to break the power of the devil, because sickness is caused by satanic oppression.
You can use that Name to break the power of the devil over the unsaved and make it easier for them to accept Christ. They'll still have to do the accepting; you can't do that for them.
Confession: I have the right to freedom from pain and sickness. I have the right to healing. And I exercise my rights. In the Name of Jesus, I command sickness and disease to go!
