I was reading a commentary on Apostle Paul today, and ran across this in the footnotes --- The author mentioned a quote about "Seed pickers" which he explained to mean -- "a snapper-up of unconsidered trifles. An intellectual charlatan who’s learning was second-hand and undigested." When I meditated on that I realized much of my knowledge falls under that category, but there is much that is truly considered and digested from actual experience, and that is where most of the deep and meaningful lessons are learned.

Some Christians dig and peck around the Bible and doctrinal thought, not really applying much of it, so they get distracted by trivial issues, their learning is second hand, not by personal experience from actually being involved in ministry, so they may have lots of knowledge, but it is "undigested", meaning, not tried and proven with personal experience.
