Biblical Discernment: The Duty of Every Believer
“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.” —Hebrews 5:14
The Mark of Maturity
A church that does not equip you to evaluate doctrine is a church that is content to keep you in a state of perpetual spiritual infancy. In a modern culture that often prizes “niceness” over truth, the command to discern is frequently met with hostility or dismissed as “judgmentalism.” However, Scripture reveals that the ability to distinguish between the holy and the profane is not a specialized gift for a few; it is the defining mark of a believer who has reached “full age.”
The Peril of “Aesthetic Approval”
In modern architecture, a building may look beautiful on the surface while suffering from fatal structural flaws. Similarly, many are told to overlook doctrinal errors if a sermon is “encouraging” or “sincere.” This popular advice ignores the apostolic warning that “a little leaven leaveneth the whole lump” (Galatians 5:9).
When the foundation of a sermon contains even a small fracture of error, it compromises the integrity of the entire message. Discernment is the spiritual plumb line that tests whether a teaching is “straight” according to the Word. To accept a message based on its outward appearance without testing its structural foundation is an act of unfaithfulness to the Lord Jesus Christ.
The “leaven” here refers to a false doctrine or a corrupting influence. Just as a small amount of yeast eventually permeates and changes the nature of an entire batch of dough, Paul argues that admitting even a “small” requirement of human merit into the Gospel of grace eventually destroys the entire message of salvation by faith alone. If a man seeks to be justified by the law in one point, he becomes a “debtor to do the whole law” and has effectively “fallen from grace” (Galatians 5:3-4).
What is Biblical Discernment?
True discernment is the God-given ability to think His thoughts after Him. It is the disciplined skill of separating truth from error, not based on personal feelings, cultural popularity, or the charisma of a speaker, but based exclusively on the written Word of God.
- It is Objective: It relies on the fixed standard of Sola Scriptura.
- It is Necessary: The New Testament is filled with warnings against false teachers who appear in “sheep’s clothing” (Matthew 7:15).
- It is Loving: Because “charity… rejoiceth not in iniquity, but rejoiceth in the truth” (1 Corinthians 13:6), identifying error is the highest form of love for the sheep.
The Boundary of Righteous Judgment
We must be careful to judge according to the biblical boundary. We do not judge the motives of a preacher’s heart, for the Lord alone “searcheth the hearts and trieth the reins” (Jeremiah 17:10).
However, we are commanded to judge the fruit of the lips—the specific doctrines, interpretations, and applications proclaimed from the pulpit. If the “fruit” does not align with the Root of Scripture, we must mark it accordingly.
Next Step: Practical Application
How do we move from the duty of discernment to the practice of it? We follow the example of the noble Bereans. We receive the word with readiness of mind, but we submit every word to the daily scrutiny of the Scriptures.
