And when they bring you unto the synagogues, and unto magistrates, and powers, take you no thought how or what thing you shall answer, or what you shall say:
Read Chapter 12
Basil the Great
AD 379
The Christian should not fear or be distressed in difficult circumstances and thus be distracted from trust in God. He should take courage as if the Lord were at hand directing his affairs and strengthening him against all his adversaries. It is as if the Holy Spirit were instructing him even as to the very replies he should make to his enemies.
"And when they bring you before synagogues, and rulers, and powers, think not: beforehand how ye shall make your defence, or what ye shall say. For the Holy Spirit shall teach you in the same hour what ye must say."
You must also know that the Holy Spirit empowers the martyrs to bear witness…. A person cannot testify as a martyr for Christ’s sake except through the Holy Spirit. If “no man can say ‘Jesus is Lord,’ except in the Holy Spirit,” will any man give his life for Jesus’ sake except through the Holy Spirit? Catechetical Lectures
When "brought before magistrates "and examined, He forbids them "to take thought how they shall answer; ""for "says He, "the Holy Spirit shall teach you in that very hour what ye ought to say."
