You need both. They both serve an important purpose for self-preservation. But, you never forgo fact for faith.
That's why I said
I think if we ask, what are facts, and we have the correct understanding of what facts are, then we would realize that facts and faith are not at odds with each other, but can be quite compatible.
To illustrate...
So someone says to a man, these are the facts. Your wife's cheating on you. She's no good.
The man believes the "facts"
(so-called). He's gullible.
He investigates the "facts"
(so-called). He's reasonable and sensible.
What does his investigation of the "fact" reveal?
The "facts" are determined by circumstantial evidence alone.
No one saw his wife cheating on him, but assumes that she is, and concludes that she is no good.
If the man believes the "facts". He's gullible.
The man trusts that his wife is not cheating on him, not blindly, but based on the evidence he has of his wife - reasons that led to him trusting her enough to marry her in the first place. I say that man is sensible.
The facts may well be, that the wife is faithful, but there are certain circumstances that give the appearance, that she is not.
The man sticking to his wife, does not put facts and faith at odds, but demonstrates how evidence can be distorted, but faith has supporting evidence, and is rational.
People tend to think they have facts, when they really don't. They often believe in things because they want to, not because they have direct evidence - proof.
I may see a man's wife go into an apartment with a man. Right away, I jump to the conclusion they are having an affair, and may feel that this evidence is too strong to deny my conclusions are facts... but are they? Have I reached the right conclusion, or perhaps is it the case that this is what I want to believe - what I want to be true? Maybe I want the relationship between the husband and wife to end. Maybe... So many maybes, but I don't have the facts, do I?
So we must be careful we understand and identify what a fact is, before concluding that facts are at odds with faith.
