Hebrews 5: Maturing As Christians
Just like physical maturity, spiritual maturity is something that happens over time. In Hebrews 5, we hear about the difference between milk and meat.
Heb 5:12 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.
Heb 5:13 For every one that useth milk is unskilful in the word of righteousness: for he is a babe.
Heb 5:14 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.
I think there are a few important things to pull out from here. First, there is nothing wrong with needing milk. Those people might be unskillful in the Word, but it is not mean they are not of the Word. That is an important differentiation. Young Christians are still Christians, and that puts them in the family. They certainly need to learn more about the ways of God, but it is not as if they need to meet some type of maturity threshold before being allowed to be Christians.
For this audience however, the author is saying that they should be further developed by now. Again, it is not that the fundamentals are wrong, but development is natural. Just like people mature physically, they should also mature spiritually. As they live with the God longer, they should understand more about God and have a better handle on good or evil. It is not that we become perfect right away, but we start to move in the right direction.
I wonder where I am or where you are on this continuum. The vital part is that we are on continuum. Again, even if we are young Christians, we are still Christians. However, just like developing physical maturity brings about certain benefits and privileges of adulthood, there is more joy to be gained through a closer relationship with God.
