First let me acknowledge this statement, and also that I've heard it from many people, so it's a widespread reply to 'faith being to trust in something before it is seen'.
Now, there is an
kind of evidence (suggestive, or for some even a kind of powerful indication) that there is at least something that is a
good one can see ahead of time (put some initial small beginning trust into), in Christ's central and clearly emphasized words which He himself highlights as central. For example:
Matthew 7:12 In everything, then, do to others as you would have them do to you. For this is the essence of the Law and the Prophets.
(of course it is good to treat others as well as you want them to treat yourself. To do for them what you'd want done for you if you were in their very specific situation they are in -- in their shoes).
Or:
Mark 12:31 The second is this: 'Love your neighbor as yourself.' No other commandment is greater than these."
(to love your neighbor is 1 of the 2 "great commandments", those singled out as above the level of all other commandments)
So, there is a kind of evidence of 'good' to initially put a certain initial level of trust in, according to your life experience or such, to the extent you can recognize why these are extremely beneficial -- humanistically good.
We actually agree on that fully. As I see it, initial 'faith' is a 'leap of faith' -- precisely like....
...what you would need to establish any relationship past that with your own mother.
In order to establish friendships or a lasting love, with anyone practically, you need an ability to take some modest, moderate leap of faith, trust, on a modest level -- more than zero trust. (if you continued over time to have zero trust, you'd never give an opening to real friendship to the person, not even after months....)
So, that
"trusting in something that hasn't been proven" is crucial, necessary to ordinary life, such as to finding a spouse.
