Here is a video of John Wimber teaching and serving at the same time.

Last year the Reading Vineyard (UK) brought healing to the streets. Here is a video of the event including some testimonies.

Randy, a former Vineyard pastor, is the founder of Global Awakening, whose vision is to fulfill the biblical commissions of Jesus:

• As you go preach, saying the Kingdom of heaven is at hand. Heal the sick, cleanse the lepers, raise the dead, cast out demons. Freely you have received, freely give. Matthew 10:7-8
• Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age. Matthew 28:19-20.

Here is a helpful guide written on how to pray for someone with cancer written by Teresa Seputis. She provides some elements to include when you pray for someone with cancer:

• Command the cancer to leave.
• Command the obvious symptoms to leave as well (command pain to leave, if there is congestion in the lungs then command it to clear up, if the person is too nauseous to eat then command nausea to go, etc)
• Command proper functionality to return to the effected body part.
• Bless the effected body part to function the way God created it to.
• Forbid cancer cells to multiply.
• Forbid cancer cells to use the sugar in the blood that the healthy cells need. (Cancer cells use all the sugar in the blood stream and starves the healthy cells so they die, and the person becomes very weak).
• Curse the cancer cells and command them to die and pass outside of the body without hurting any healthy cells.
• Bless healthy cells to live.
• Break any curse of death over the person and speak life to them.
• Break any general access that either cancer or a spirit of death may have over the person.
• Command any spirits of cancer or any spirits of death to leave, and be sure to cancel their assignments. Sometimes when I do this a powerful demon manifests and I find myself in a full out deliverance ministry. If that happens, it is a good sign, because once that demon is gone, a lot of the cancer symptoms leave with it. Do don’t be afraid if a demon manifests when you pray this… just use the authority Jesus gave you to command it to leave.
• Command any spirit of fear to leave — often when a person gets a traditionally “fatal” sickness, a spirit of fear tries to come in and set up residence.
• Ask the Lord to come with His wonderful healing presence and complete the healing and work His glory in the sick person’s body.
• Ask the Holy Spirit to come fill and encourage the person and to minister to them.
