practiced Biblical Christian life is about a relationship with God, it’s a love thing. Because He first loved us, we love him and want to live in a way that honors him (as the hymn goes) “for His glory
and our good”.

And the first step is the biggie: choosing to believe in God and His son Jesus. Nothing else happens before that, no understanding, no faith, no spiritual growth et al. It’s after that we feel the proof.
“Faith has to be tried before the reality of faith is actual.” But, it’s a journey where one is actually seeking to know. Bible Study, prayer, hearing the preached Word of God (as opposed to homilies and subjective experiences). Then fellowship with other believers plays a key role in the journey, the growth, the maturity. It is a lifestyle.

It seems to me that belief in science alone is a method that gives only what can be observed, what is tangible, but does not offer a moral compass, a clear definition of good and evil, but more important to me is the very real presence and guidance God gives.

I have non-believers in all generations in my family and for the most part they’re all good people, and We love each other. But the ones who have influenced my thinking and made me want what they had in terms of relationships, responses to life’s problems
are Christians.

I don’t expect you to understand that. But that Christian label doesn’t always mean a life lived Biblically. And a life lived Biblically is not a perfect life, but a journey, often a struggle, to follow Christ. So if you’re judging Christianity by examples other than a purely Biblical one, it doesn’t represent Biblical Christianity, which, imo, is necessarily the correct representation.

That’s why I consider non belief as limited, very limited.
