Considering that this is exactly how it works "in real life," this is an excellent way to write relationships in your story.
We rarely realize it, but our relationship with God directly affects our relationships with the world and others. The reverse is also true--someone's approach to faith usually says a lot about their past experiences, worldview, etc. Examining one can usually give you diagnosis for the other.Putting more focus on the earthly relationships can also help make your story more marketable and readable in some cases. Portraying religious concepts in direct, overt language can be difficult. Coming at it indirectly through other relationships in the story can make it easier to swallow for some readers. The movie Zootopia did this with the theme of racism. Instead of having a movie with classic black and white people hitting on the themes of racism--which would have been difficult to pull off--it used animals and their made-up social classes to indirectly talk about racism and sexism. It would have been very, very hard to get past people's "knee-jerk reactions" and prejudices if they'd made a movie with people. But since nobody has racist prejudices against rabbits and foxes, Disney was able to very easily portray racist stereotypes in a way that the audience would swallow (and even enjoy).
All of that to say--keep up the good work.
