It's their faith that makes them whole right? So do these Christians not have real faith in Jesus? He only said a tiny amount of faith would cure you, so I'd expect that lots of Christians would be made whole.
It's our
faith that makes us whole? No. It's what our faith is in that makes us whole. Having faith in a rock, or a mound of dirt, or some bread mold to make me whole isn't going to work. Only those in Scripture who had faith, who trusted,
in Christ were made spiritually - and sometimes physically - whole.
Do Christians not have real faith in Jesus? Many of them don't. Perhaps a majority. That's because most of them merely exercise intellectual assent, rather than saving faith, in Christ. What's the difference? The apostle James explains,
James 2:19-20
19 You believe that there is one God. You do well. Even the demons believe--and tremble!
20 But do you want to know, O foolish man, that faith without works is dead?
Real, saving faith expects, or aims at, a corresponding effect in behaviour. It's one thing to agree that wearing a life-jacket can save you from drowning when out boating; it's another to believe it will save you and then
actually put the life-jacket on even when its hot, and looks a bit goofy, and all those around you are using their life-jackets as seat cushions. Simply agreeing to the truth of the life-jacket's effectiveness in saving you from drowning is intellectual assent; going beyond acknowledgement of this truth to
taking action based on that truth is, according to the apostle James, "saving faith." The majority of "Christians" acknowledge that Jesus is God and the Saviour of all men (and women), but precious few of them shape their lives in accord with this truth. They hold a belief about Jesus, but they have no intention of fully conforming their lives to it. They want heaven by-and-by, but not Christ as Saviour and Lord over them right now. As James points out, such belief is no more than what demons possess.
He only said a tiny amount of faith would cure you, so I'd expect that lots of Christians would be made whole.
A tiny amount of the
right kind of faith, in
the right thing (that would be Jesus) can reconcile a rebellious, wayward sinner to God. Many Christians these days, though, have been encouraged into what has come to be called "easy believe-ism." Simply pray a prayer of acceptance of Jesus and you're in God's family. And many have. But there is no confession of, and repentance from, sin; no counting the cost of taking up the cross of Self-sacrifice in emulation of Christ and then doing so; no understanding of the new life in Jesus; no surrender to God; no love of God, only a desire for the eternal life He offers. But this isn't the Gospel of Salvation that the Bible teaches; such a prayer ignorant and/or careless of these other things does not obtain salvation for anyone.
Selah.
