Jesus did not say the kingdom of God was like a man who believed there was a treasure hidden in a field. “Now that I know there’s a treasure in that field, my life is changed! I’m now completely debt-free simply for knowing this information!”

Uhhh, no.

We have equated spiritual belief with mere intellectual assent. From what I’ve studied, when Jesus or the apostles spoke of “belief” in their day, they meant something you stake your life on.

You sell all you have for that field to get the treasure in it.

That is trust.

Acknowledging the treasure without obtaining it is non-life-changing erudition.
