Is it NOT merely TRUST in your Spouse rather than FAITH that you have perhaps?
Do you have TRUST that your Spouse is true to you and you alone rather merely having the FAITH that he/she really is?
The word FAITH is a very ambiguously used word is it not, with almost countless meanings, etc.
Whereas 'TRUST' is an instinctually driven emotion that is derived and grows from knowing from experience, knowledge and skills, etc, etc, gained for example.
We LEARN to TRUST ourselves and others from what we experience from them, the same goes with our own abilities, skills, talents, capabilities and the like.
We TRUST that others will treat us as we treat them and TRUST that are as decent as we are BUT we learn about them through trusting them as we go along.
To my way of thinking, WHEN a person says to, " Have Faith in me," it rings instinctual Alarm bells because cannot be earned where Trust has to be earned.
The old saying, "A Leap of Faith" imo, means simply " Don't look, don't think, just do and hope for the best," somewhat akin to the old adage about when someone shakes your hand and pat you on the back and says, " Have Faith in me," IS he/she merely being friendly OR is he/she simply using his/her free hand to seek out the best place in which to stab you in the back?
Conversely, imo, when someone tells me, "Trust me," I see as being that THEY are putting THEIR reputation on the line with those words rather than using a bit 'banter' to ease your doubts, etc.

@Triphid I see trust and faith as synonymous. I’m sure there are nuances, but I will leave that to the lit majors on here.
In either case I see they must be earned or some experience that
leads to the creation. I suppose a leap in faith applies as well.

@Canndue But, is NOT Faith merely a type of belief/believing WITHOUT any Evidence, etc, to support it, whereas ACTUAL Trust is an understanding/emotion based on previous experience/, knowledge and shown/ visible evidence/s?

@Triphid possibly, I was only expressing my view on it. But maybe that should be called blind faith?

@Canndue In my somewhat educated opinion here, Trust is something that is gained, earned, learned, etc, etc from lessons, experiences, etc, and can be often relied upon.
Whereas Faith, for example, is based SOLEY upon either Wishful/Hopeful thinking OR, in the case of Religious beliefs, something that one is TOLD that one MUST have or thrust upon you by those around you, i.e. " Blind Faith."
It is easier for 'faith' to let you down when you most need it than it is for 'trust' do so, imo.
One can have TRUST in a Mechanic, Electrician, Builder/Carpenter, etc, etc, because he/she has, more often than not, the documentary evidence and previous tasks available to SHOW that he/she IS Trustworthy.
Whereas, on the other hand, FAITH is merely nothing more a Presumption/Assumption that it IS there.

@Triphid
Like many words, there are multiple uses. Since I have no religion, I use it in reference to #1. But, it is a free world.

1a : allegiance to duty or a person : LOYALTY
lost faith in the company's president
b(1) : fidelity to one's promises
(2) : sincerity of intentions
acted in good faith
2a(1) : belief and trust in and loyalty to God
(2) : belief in the traditional doctrines of a religion
b(1) : firm belief in something for which there is no proof
clinging to the faith that her missing son would one day return
(2) : complete trust
3 : something that is believed especially with strong conviction
especially : a system of religious beliefs

@Canndue Fair enough, so let us agree to disagree on this subject shall we.

@Triphid works for me

Could that not be simply TRUST rather than Faith?
For example, When I make a cup of coffee I trust that the Coffee is in the pod, the machine is connected to the Electricity, the water is in the tank on the machine and my cup is in place under the machine.
I do NOT have FAITH that all those things are there and ready to go.
The same goes for when I build something, I do NOT have mere faith that I can do so, I trust that my knowledge and skills have made me able and capable to do so.
