I think this is a common misunderstanding among Charismatic and Pentecostal Christians. Albeit a well founded misunderstanding, I think this is a misunderstanding all the same. To some degree it comes back to the question of how much are we empowered to do on our own versus how much we are completely reliant on Jesus to do things for us/through us.
You have the man who was lowered into Jesus’ presence by his friends and the text says “Seeing their FAITH, Jesus told the paralytic “Son, your sins are forgiven.” Likewise with the hemorrhaging woman Jesus says “Your faith has healed you.” And with the Roman Centurion Jesus says “Go. As you have believed it, let it be done for you.” The problem with this train of thought is that it becomes exclusive and it then becomes reliant on someone already in agony to receive healing.
It’s never that Jesus hasn’t healed you yet, it’s that you haven’t received healing. You don’t want to be healed. You don’t believe enough to be healed. All of a sudden the question isn’t about “why hasn’t God healed me?” but it turns into Job and his three buddies saying “why don’t you believe you’ll be healed? Clearly you don’t believe or you would have been healed by now!”
Everything becomes the fault of the person who is afflicted who isn’t praying the right way, doesn’t have enough faith, or has to overcome some kind of generational sin. Now don’t get me wrong, all of those things can play a part, but I get annoyed whenever people start talking about “having enough faith.”
Jesus said “If you have faith the size of a mustard seed [1/20 of an inch] you can move mountains.” In other words, if you believe that Jesus died for you while you were still a sinner so that you might have life then you have enough faith to be healed.
Do you believe Jesus is compassionate?
Do you believe Jesus loves you?
Do you believe Jesus died and rose again?
Do you believe Jesus will come again some day?
Do you believe that Jesus is the Son of God, the Word made Flesh?
If you answered yes to any of these questions, then you have faith enough to receive healing. You have enough faith to facilitate the healing of others. You have enough faith for signs and wonders. You have enough faith for Jesus to show up in your living room for tea and biscuits. You have enough faith to move mountains and do GREATER THINGS THAN THESE.
Don’t let anyone else tell you otherwise.
