What is spiritual discernment?
"Dear friends, do not believe every spirit, but test the spirits to see if they are from God, because many false prophets have gone out into the world." — 1 John 4:1 CSB
"But solid food is for the mature, for those whose senses have been trained to distinguish between good from evil." — Hebrews 5:14 CSB
Spiritual discernment is the ability to distinguish between what comes from God and what does not, applied both to the teachings we encounter and to the direction of our own lives. The Bible commands all believers to discern, not just those with a particular spiritual gift. John tells us to test the spirits, and Hebrews tells us that discernment grows in people whose senses have been trained through regular practice in Scripture and prayer.
Why John Says "Test the Spirits"
The command in 1 John 4:1 arrives in a specific context. John was writing to a community that had been disrupted by teachers who claimed spiritual authority but were quietly leading people away from the truth about Jesus. These teachers were not always obviously hostile. They were presenting themselves as voices worth listening to, and some in the community were listening. John's response was not to tell his readers to close themselves off from all outside teaching. It was to give them a test.
The world John wrote to has not changed in this regard. We live in an era of extraordinary access to teaching, content, and voices that claim to speak for God. Some of them are faithful. Some of them are not. The command to test the spirits is not a suspicious posture toward everything or an invitation to constant skepticism. It is a responsible and loving instruction to take seriously what we allow to shape our understanding of God and ourselves.
What Spiritual Discernment Actually Is
Some Christians hear "spiritual discernment" and assume it refers to a special gift given to a particular few. And 1 Corinthians 12:10 does describe a specific gift of distinguishing between spirits, given by the Holy Spirit to some members of the body. That gift is real and the church needs it. But the command to discern is not addressed only to those who have received that particular gift. John writes to "dear friends," the whole community, and tells all of them to test the spirits.
The discernment John is talking about is also not a natural ability to pick up on the vibes of a situation. Unfortunately, that’s a common misunderstanding. We shouldn’t mistake our natural intuition for spiritual discernment. Similarly, it’s wrong (and dangerous) to attribute divine authority to our own biases. God isn’t calling us to judge someone’s motives based on our biases or our feelings and call it spiritual discernment.
The discernment the Bible is talking about in the passages above is a supernatural ability that we are instructed to develop through the Holy Spirit. John says some people have fully formed it and others have not, but his teaching is that we all can do this work. Discernment is a capacity that every believer is called to develop, through knowing Scripture, through prayer, and through honest community with other followers of Jesus who can speak into your life. Hebrews 5:14 describes it not as something received fully finished but as something that grows in people whose senses have been trained by practice. This kind of discernment is a discipline and a gift.
How Discernment Grows
Hebrews uses the image of training, and that‘s very helpful. The way a person develops a trained sense for anything — music, medicine, a skilled trade — is through repeated, attentive exposure to the genuine thing until counterfeits become recognizable by contrast. Discernment grows the same way. The person who knows Scripture well, who has spent time with the words and character and promises of God, is the person who notices more quickly when something being taught contradicts what is true.
This is one of the practical reasons to stay in Scripture even when it doesn't feel spiritually productive. You are not just gathering information. You are training a sense for truth. The person who reads the Bible regularly, not because every session is emotionally moving but because they are genuinely trying to know God, is accumulating the kind of familiarity with truth that makes discernment possible. Honest prayer that brings real questions to God builds the same capacity — a practiced posture of dependence and attentiveness that makes a person more sensitive to what is genuinely from Him.
The Test John Gives Us
When John gives his community a test, it is focused entirely on Jesus. The Spirit of God, he says, will confess that Jesus Christ has come in the flesh. Any spirit that does not confess Jesus is not from God. The three parts of that test — that Jesus is the Christ, that He is divine, and that He came in real human flesh — are straightforward but searching. You can apply them to any teaching you encounter: does this consistently draw me toward the real Jesus, or does it redirect my attention toward something else? Is the Jesus being described here the Jesus of the New Testament, or a more comfortable version with the challenging parts removed?
The test is not designed to make you suspicious of everyone. It is designed to give you an anchor. When you know what the Spirit of God will always affirm about Jesus, you have a reference point more reliable than your feelings about a particular teacher's delivery or the size of their platform.
What Discernment Looks Like in Daily Life
Discernment in daily life is less dramatic than the phrase "testing the spirits" might suggest. For most of us, it does not look like confronting false prophets or detecting hidden spiritual forces. It looks like the accumulated pattern of choices about who we allow to speak into our lives and what we do with what they say. Whose teaching are you regularly sitting under? Is the Jesus that teaching describes the same Jesus you find in the Gospels? Is Scripture the foundation of what is being built in your life, or is it a decoration on top of something else?
These are the practical questions discernment asks, and they are worth returning to periodically rather than assuming everything is fine because nothing feels obviously wrong. The security to ask them honestly comes from knowing that your identity is already settled — you are loved and held by God, and nothing about examining these questions puts that in jeopardy. You are not being evaluated. You are being equipped. And that is entirely consistent with the character of a God who commands you to discern because He genuinely wants you to know what is true.
God is not trying to confuse you. He has given you His word, His Spirit, and His community of believers, and He has commanded you to use all of them together in the work of discernment. The command to test the spirits is not an expression of suspicion about everything. It is an expression of love from a God who wants you grounded in truth and not carried away by every voice that claims authority. Discernment grows in the person who practices that seriously, and He promises to guide the one who is genuinely looking for Him.
