Good points, but something significant is missing.
Notice that Michael Brown at minute-1:40 does not include the important third verse in James’ healing passage in chapter 5, that says we must confess our sins one to another to be righteous, to be healed.
14 Is any among you sick? Let him call for the elders of the assembly, and let them pray over him, anointing him with oil in the name of the Lord, 15 and the prayer of faith will heal him who is sick, and the Lord will raise him up. If he has committed sins, he will be forgiven. 16 Confess your offenses to one another, and pray for one another, that you may be healed. The insistent prayer of a righteous person is powerfully effective.
It should go without saying that the elders who are praying have also confessed their sins to one another, so are clean, according to the elders’ qualifications that require them to be “blameless” and “holy,” and Paul’s own example in Acts 24:16:
“Herein I also practice always having a conscience void of offense toward God and men.”
I’m finding out that more often than not, those who quote this James-5;14 passage usually leave out this crucial verse 16. Unless one has reconciled with everyone they know they should, verse 16 is an uncomfortable passage that many avoid. But we must not. Lack of reconciliation and holiness is probably the main reason why so few are healed today, unless the illness is demon caused, because it’s fairly easy to drive out demons.
Can We Command Sickness to Be Healed?
