Really, where? Did he forget to pack it with the tent making tools?Paul lost his gift to heal for Timothy...
What makes you think that Paul needed to "heal" Timothy when it was obvious he could not heal himself? Why was not Timothy's condition just as much a "thorn in the flesh" as Paul's and didn't need "healing?"
When you pray in the assembly for one to be "healed" do you actually mean what you pray?
Paul looked at a man and saw the man "had faith to be healed." It does not say Paul healed him.
Do not assume I am making light of the account in Acts 14. Rather, that there is no statement as to a diminishing capacity for a righteous man being led according to God's purpose.
Rather, that as James would declare, "the prayers of a righteous man avails much." Was James wrong? That passage is directly related to healing.
If one hides no iniquity in their heart as to hinder, and of righteousness prays, is God unresponsive or is He compelled by His authority to respond?
