**sigh** ...R.Miller, only in a semantically twisted way can we can say that faith is "trust without proof." More specifically, to phrase it this way is to make it sound as if the typical Christian has
absolutely no Epistemic Indicia in life by which to identify Christ as Lord and so choose to follow Him. In my estimation, and speaking as a Critical Realist advocating the application of Philosophical Hermeneutics to all of life and human thought, including to the varieties of skeptical/atheistic thought, this kind of skeptical evaluation is disingenuous and, if anything, might mean that you need to stop giving too much credence to the Street Epistemologists [Dogmatic-Foundationalists] or atheists of other epistemological ilk upon whom you may be over-indulging.
More accurately, we might say that
Christian Faith is a positive Aesthetic response to Jesus Christ, one that emerges out of a person's whole being in the ongoing processes of living the daily existential Christian life, which includes a psychological confluence of multiple sources of influence, partially epistemological, partially metaphysical, but all dependent on one's own personal expectations that come to bear out the dynamic of one's own Hermeneutical understanding.
Sure, there's always the issue as to whether we each individually think the evidences for Christian faith are sufficient or not--and for some people, if not many, the evidences may very well seem utterly lacking--but let's not kid ourselves into thinking that sufficiency in relation to Christianity is some kind of Objectively determined level of epistemic justification out of which comes a (supposedly) resulting sense of subjective satisfaction, because it's not! This is especially the case if we move from the all-too worn and travelled Exterior epistemic issues to barely considered Interior epistemic issues that are inherent to the thought of the various biblical writers [by which I'm now referring to the additional field of Biblical Epistemology].
At this point I'm going to halt since all I'm really trying to do is impart some friendly advice to you for your benefit rather than to debate. If anything, I'd like to suggest that you reevalutate the epistemic principles and praxis by which you think you're supposed to assess and value the essence of Christianity. Remember, you're not trying to build a spacecraft by which you'll land on the face of Mars; no, you're trying to somehow reach out and encounter the Spirit of the Living God as it has been revealed through the person of Jesus Christ, however that is supposed to happen for each one of us, and this latter project is of a different kind of human experience than is, say, working at NASA or SpaceX. There may be more for you to consider than you've been told, or up until this point, than you have been willing to engage.
On the other hand, I'm not going to sugar-coat it and tell you that you won't ultimately still be disappointed with what you find in Christianity on the whole. The fact is, some of our eventual satisfaction with the Christian faith will be partially determined by what we each "wish" to find there, and if we're the kind of person that is coming to Christianity to gain health, wealth, prosperity, and/or the uber kind of life, I can only shake my head in pity.
Peace,
