When Jesus told his disciples not to worry how they would respond when they were imprisoned for their faith, he did not say not to study, but not to worry (Mark 11:13; Luke 12:11). Moreover, the disciples had studied and lived with the Master Teacher for about three years before his statement. They were already well-equipped to produce under pressure.
Reliance on the Holy Spirit does not mean being an ignoramus, or, in jazz lingo, not “spending time in the woodshed.” Instead of reciting talking points (like talking heads), the apologist should engage conversation points through the exchange of ideas. Sparks fly and may ignite the friendly fires of truth. Truths of God that were initially only opposed or considered may become knowledge through patient persuasion inspirited by the Spirit of Truth. —Doug Groothuis (From, How Jazz Can Shape Apologetics)
