Right - so why would it be any different today? Why wouldn't unbelief still be a cause?
But it isn't.
The man who had the demon possessed son said to Jesus, "IF you can ......"
Jesus replied that everything is possible for the one who believes. And the man answered, "I do believe, help me in my unbelief". Jesus was standing right in front of him, and he still said, "IF you can"
and confessed some unbelief.
The man at the pool of Bethesda did not confess faith in Jesus. He had faith in a superstition that an angel occasionally stirred the waters and anyone who then entered, was healed.
But Jesus granted healing to both.
We already have more faith than they did.
We cannot see Jesus yet we believe in him, believe that God answers prayer and that he hears us.
We cannot see, but we believe, John 20:29, Hebrews 11:1, Hebrews 11:6.
People who met Jesus did not necessarily believe - even when he was standing right in front of them. Nor did Jesus always ask them about their faith.
We who have not physically met Jesus and cannot see him, pray; believing in his power, that he saves us, that he answers prayer. Some fast and have hands laid on them, etc.
But not all of them receive physically healing - either at the time they ask for it, or later.
He also did NOT say only some would be healed - He also did not say healing is for only certain people - He also did not say healing was not His will - and He never said no to someone who asked for healing.
And yet some today, ARE told "not yet", and/or not granted healing.
Fact.
We walk by faith, not by sight.
We, who have the cross, the empty tomb, the Holy Spirit, the whole of the NT, the witness of thousands of Christians etc etc, are sometimes asked to trust God, even though we do not see the results of the things we pray for.
I never said anyone did, yet this seems to be stuck in your mind. Not sure why - but I have never preached, read or taught it.
I don't think I said that you did.
But this is what I have heard from others on these forums who also believe that God always heals Christians today.
Sorry if I implied that you believe this too and you don't.
But the argument has been; God always heals - due to the verses and reasons that you have given. God doesn't lie.
So when someone prays for healing, they ARE healed from that point and have to live by faith - i.e that they have been healed. And not by sight - i.e that they still have their symptoms.
This usually involves urging the sick person to refute, their symptoms and to declare over and over again that they ARE healed.
Jesus never told people to do that.
Again, sorry if the above does not apply to you.
