Matthew 12:33
33“Either make the tree good and its fruit good, or make the tree corrupt and its fruit corrupt; for the tree is known by its fruit.
Jesus refuses a split verdict: good tree with bad fruit, or bad tree with good fruit. Nature and produce belong together; the tree is known by what it yields.
Arminians hear both diagnosis and summons. Grace can renew a diseased tree so that good fruit becomes true; hearers remain responsible to stop pretending that bitter speech somehow grows from a healthy root. Either reading: fruit reveals the tree.
The proverb is christological confrontation, not a gardening tip. Make the tree good or make it bad—Jesus binds fruit to nature and exposes their charge against Him as incoherent.
Trees produce after their kind. Recognition by fruit is God’s appointed honesty about the heart. The saying prepares the sharper word that follows: evil mouths cannot suddenly speak as if the tree were sound.
Key contrast Both confess that fruit reveals the tree. Arminians commonly stress grace that can renew the tree and the hearer’s responsibility to bear good fruit; Reformed readers commonly stress that fruit exposes a nature already good or bad under God’s truthful verdict.
