King James Version (KJV)

Read Full Chapter →A courtroom, interrogation, or public accusation can make faithful people fear that they will have no words. Jesus promises to be actively present in their testimony. His gift is sufficient for witness even when opponents retain power to reject, punish, or kill the speaker.
Jesus promises persecuted disciples Spirit-given speech and wisdom that hostile examiners cannot successfully refute, enabling courageous and faithful testimony under pressure.
The Context of Luke 21:15
Jesus is teaching in Jerusalem during the final days before His crucifixion. After observing a poor widow's offering, He responds to admiration of the temple by predicting its destruction. His disciples ask when this will happen and what sign will precede it. Jesus warns against deceivers, panic over wars, and premature claims that the end has arrived. Before broader upheavals, His followers will face arrest, imprisonment, and appearances before rulers because of His name. Verse 13 says persecution will become an occasion for testimony, verse 14 tells them not to prepare an anxious defense in advance, and verse 15 promises Christ-given speech and wisdom. Betrayal, hatred, death, and patient endurance follow.
What Does Luke 21:15 Mean?
'I will give you' makes Jesus the direct source of what His disciples need. A 'mouth' means the capacity and words to speak, while 'wisdom' gives fitting truth, judgment, and direction to that speech. The promise addresses testimony under persecution rather than every debate or ordinary presentation. Opponents will be unable to 'gainsay nor resist' the truth and wisdom of the witness. They may still refuse it or use force, as the next verses make clear. Irrefutable testimony does not guarantee acquittal, popularity, or physical safety; it means hostile power cannot make faithful truth false.
The command in verse 14 against premeditating an answer addresses anxious self-reliance in the crisis. It should not be used to excuse careless teaching, dishonest improvisation, or refusal to study Scripture. Luke elsewhere commends learning, careful testimony, and reasoned proclamation. Here disciples brought suddenly before authorities can trust that Jesus will not abandon them to their own resources. Acts repeatedly displays this gift as Peter, Stephen, Paul, and others speak with courage and scriptural wisdom before councils and rulers. Their hearers sometimes respond with faith, sometimes with rage, and the promised witness remains real in both outcomes.
Jesus' promise is personal: the One for whose name they suffer gives what they need. In Luke 12, He attributes courtroom instruction to the Holy Spirit, showing Christ's provision working through divine presence rather than a memorized technique. This gives persecuted believers dignity and courage while placing limits on confident outsiders. We cannot prescribe exact words for someone facing danger or shame them for seeking legal help. We can pray, accompany, provide counsel, and trust Christ to sustain their truthful voice. The purpose is faithful testimony, shaped by His wisdom and free from manipulation or revenge.

Where Luke 21:15 Echoes in Scripture
Acts 6:10 says Stephen's opponents could not resist the wisdom and the Spirit by which he spoke. His later martyrdom shows the precise shape of Jesus' promise: truthful and Spirit-given witness can remain unanswerable even when hostile hearers choose lethal violence.
How to Apply Luke 21:15 Today
Prepare for difficult testimony through ordinary faithfulness: learn the truth carefully, keep records, practice concise speech, and build relationships with wise supporters. When crisis comes, pray for words that are accurate, courageous, and free from needless aggression. People facing legal or institutional danger can seek qualified counsel; trusting Jesus and receiving practical help belong together. Communities should accompany persecuted witnesses materially, emotionally, and publicly rather than merely admiring their courage. If opposition continues despite a clear answer, measure faithfulness by truth and love instead of the opponent's reaction.
Reflection & Prayer
