I've been asked in the past if I could leave Jesus out of my story...course the answer was no...and they passed.

Robin,
There’s no fundamental reason why the point, or period, at which Jesus transformatively enters your life -- which remained faith-based thereafter -- would need to be excluded at all.
To be a successful film, you’re dealing with biopic story material that at its core almost certainly features a period of derailment of personal life and career life purposes, a transitional internal re-assessment, and ultimately the certainty of satisfactory (to yourself and general audiences) redemption.
These exact elements are entirely relatable on an inspirational human level -- regardless of the extent or nature of the viewers’ religious beliefs, or absence of personal religiosity -- and are the substance of countless feature films and made-for-TV movies dealing with depression, and any serious interactions with substance abusers (alcohol, drugs, medications) and always in the many award-winning stories dealing with redeemed criminality in political, financial, legal, or just about any societal worlds.
In my experience, the screenwriters’ time-tested key is to vividly present the challenges, effects of wrong decisions, eventual self-realization, and related positive reasons for a life re-direction in the form of new associations and an initially-resisted guiding character (or characters) who not uncommonly, are a blend of the lead character’s new supernatural and real-life “purity-personified” love/admiration/devotional interests.
Virtually all sports-related films and most other biopics contain such progressions and not least, crucial periods of self-doubt.
Audiences root for such emotional triumphs and to the degree that the challenges, downward spiral, and positive alternatives are movingly portrayed, worldwide audience can internalize them to their own lesser challenges overcome, or simply delight in escaping into (being entertained by) a well-told story about specific worlds to which they’ve never previously been exposed.
In short, intelligent directors and screenwriters can readily convey a character’s reception of reformative spirituality by providing the character with believable gestures, acts, decisions,
memorable and meaningful dialogue, symbols and purposeful locations and behaviors (kneeling, praying, looking upward with new understanding, viewing and handling religious symbols and artifacts, etc.) and strictly*avoiding* stereotypical “choir sings in the background” musical background effects.
The handling of self-doubt, spiritual need, and actual religious dependence before the eventual triumph was expertly and deftly handled in “Rocky” and countless other sports-related films (a hero literally on his knees, praying, visibly acknowledging a very human and personal need for help that goes well beyond the well-intended assistance of the hero’s adviser characters in a given film.
A life now daily and totally transformed by a religious conversion (such as yours) is readily, absorbingly and potentially profitably portrayable by a sufficiently skilled writer, director, and impassioned actors. The journey, obstacles, conflicts and visible triumph are what interests audiences, regardless of the extent or nature of religion in their own lives.
Faith-based or eventual faith-exhibiting films can be very well produced -- and perhaps even more impactfully created -- by passionate, objective and talented individuals who while not necessarily faith-based themselves, are quite tolerant and admiring of the biopic's subject and her/his journey towards deep faith.
It's essentially a matter of clearly presenting your fully-informed vision of the project and successfully transferring that vision, via intermediaries, to interested developers of the project.
