I whole heartedly agree that when the basics are in place, then a deep understanding of scripture and theology is essential for living a well ordered life. I am 110% with you.
But when the foundational values and faith are lacking, it becomes straining at gnats to swallow flies.
It reminds me a bit of that book, “Everything I Needed to Know, I Learned in Kindergarten.”
I disagree that it’s everything we need to know, and I am far from believing that we should remain on milk, as Paul said (1 Cor 3:2) but the milk must be consumed and digested and made a part of us before we grow to truly understand the meat.
