1. The Fruit Test — Judging by Works, Not Titles
Jesus did not tell us to test prophets by their résumé. He told us to test them by their fruit. "Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles?" (Matthew 7:16). A wolf can wear sheep's clothing perfectly — the right vocabulary, the right platform, the right credentials — but a wolf cannot manufacture the nature of a sheep. Titles are clothing. Fruit is nature, and nature cannot be faked for long.Paul gives us the checklist in Galatians 5. The works of the flesh are manifest: adultery, fornication, uncleanness, idolatry, hatred, variance, wrath, strife, envyings, and the like — "they which do such things shall not inherit the kingdom of God" (Galatians 5:21). Against that, the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith, meekness, temperance — "against such there is no law" (v. 22–23). Notice how simple this is. You do not need a seminary degree to see whether a man's daily life is producing strife or peace, envy or goodness. You only need to watch him long enough.
This is why James warns, "be not many masters, knowing that we shall receive the greater condemnation" (James 3:1) — teaching is a position of accountability, not immunity. A title — pastor, apostle, prophet, elder — does not exempt a man from this test; it raises the stakes of it. "A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit" (Matthew 7:18). If a teacher cannot bring forth good fruit, it isn't that he chooses not to — Jesus says he cannot, because the fruit reveals what is actually indwelling the man, not what he claims indwells him.
The hard part is patience. "The fruit is an easy way to discern them, but the problem is that you could be under their ministry for months before seeing the fruit." Fruit takes a season to ripen. That means discernment is not a snapshot judgment made from a single sermon or a single impressive testimony — it is a pattern observed over time. Don't rush to crown someone based on charisma, and don't rush to condemn someone based on a single bad day either. Watch the tree long enough for the fruit to show, then let the fruit — not the title — cast the vote.
