13 For everyone who partakes only of milk is unskilled in the word of righteousness, for he is a babe. 14 But solid food belongs to those who are of full age, that is, those who by reason of use have their senses exercised to discern both good and evil. (Hebrews 5:13–14, NKJV)
It is hard to miss the point of this passage. Spiritual growth from infancy to maturity (“full age”) occurs by learning and using the word of God. It is crucial to see that knowing God’s word is not the same as being fully grown in Christ. We can amass knowledge of the Scriptures and still be an immature Christian. Today’s passage explains that partaking of the “first principles of the oracles of God” is like drinking milk. If milk is the only thing we eat, we will not grow sufficiently. These Christians were “unskilled” (inexperienced) “in the word of righteousness.” They were not using what they were taught from God’s word. The problem went beyond not knowing the word (true, they needed to learn more, Heb. 5:11). Their failure was not using God’s word to train themselves to distinguish good and evil (v. 14). In that state, they could not be teachers of God’s word (Heb. 5:12). Similarly, we remain spiritually weak when we know God’s word but do not apply it to our daily decisions and actions. Are you unskilled or experienced in using the word of God? Strive for spiritual maturity. Train yourself to use your knowledge of God’s word to recognize both good and evil.
