Sounds like a snide reply, and maybe it is, but it's also a good question.
I suppose my point is that people are often too dogmatic and simplistic in their understanding of things like faith. First, they follow the word of some Bible teacher (usually whoever happened to be speaking at whatever church they happened to grow up in), and they believe it wholeheartedly.
There's nothing wrong with that, I suppose. And it's perfectly natural: people desperately want life to wrapped up all clean and simple and decisively and 100% certain (which is why cults have such an appeal).
Most people don't go the "cult" route in life. But I can tell you this: To my observation, a lot of people decide, "Hey, WE'VE got the TRUTH." And then they take that and it becomes an enormous source of pride for them. Which is not really a good thing. Especially when they then use their sense that they're the people with the "truth" to set themselves, in their minds, above other people.
My point isn't to try and destroy anybody's faith. But just realize this: Any time somebody tries to wrap up faith in a cut-and-dried little box, well, it's fine for you to believe the cut-and-dried version if you want, but in my experience God and faith can't be reduced to a cut-and-dried little statement of dogma and doctrine.
It is one thing to be a believer but if they have not received a witness of the Holy Spirit, why are they so committed?
They say they believe the Bible yet they are afraid of the Holy Spirit!
They would perfer to believe 2000 tradition and than to exercise faith and receive a witness from the Holy Spirit!
1Cor.2
9 But as it is written, Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him.!
10 But God hath revealed them unto us by his Spirit: for the Spirit searcheth all things, yea, the deep things of God.!
11 For what man knoweth the things of a man, save the spirit of man which is in him? even so the things of God knoweth no man, but the Spirit of God.!
12 Now we have received, not the spirit of the world, but the spirit which is of God; that we might know the things that are freely given to us of God.!
13 Which things also we speak, not in the words which man’s wisdom teacheth, but which the Holy Ghost teacheth; comparing spiritual things with spiritual.!
14 But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned.!
15 But he that is spiritual judgeth all things, yet he himself is judged of no man.!
16 For who hath known the mind of the Lord, that he may instruct him? But we have the mind of Christ.!
