Here is a series on the reasons why we don't do prayers for healing while out on the streets evangelising.
Does someone need to see a miracle to believe?
What is an unbeliever's greatest need?
Does God guarantee that a person will be healed?
Should I focus on miracles with such limited time?
How can I know someone is coming to believe for the right reasons?
Is the ordinary preaching of the gospel better than healings?
Does God have a purpose for someone's suffering?
