This ought to be discussed. Beware of unbelief because it comes in different guises.
The belief that nothing good can come of something is unbelief, so when the Lord produces water from a stone the blind cannot witness the provision of Almighty God.
The belief that something in particular always produces good is unbelief so when the Lord speaks and says, Turn to the left or turn to the right, the hard of hearing continue in error.
There is only one place to find ourselves: waiting upon the Lord and listening to His voice. If the Lord says, Do this, then we do it; if the Lord says turn from your way, then we turn from our way. The Lord has sent me to a hospital on more than one occasion. Did I balk, believing that the Almighty would never do such a thing? The Lord has spoken, saying I am sending you to this doctor... did I question Him?
No, but then I don't have a background in churchianity so this has never been an issue for me. :)
