We are children spiritually, and the "meat of the word" is about being rewarded for enduring persecution and affliction.
The meat of the word is for those who act on what they learn, I think.
Hebrews 5:12-14 KJV
12) For when for the time ye ought to be teachers, ye have need that one teach you again which be the first principles of the oracles of God; and are become such as have need of milk, and not of strong meat.
13) For every one that useth milk is unskilful in the word of righteousness: for he is a babe.
14) But strong meat belongeth to them that are of full age, even those who by reason of use have their senses exercised to discern both good and evil.
We mature when we use what we learn.
Much love!
