When Jesus foretold the coming persecution of his disciples, he said that it would turn out to the advantage of the Gospel. They would be able to testify to people who wouldn’t normally hear the Gospel. They would testify of Jesus before the authorities of the land, and before governors and kings (Luke 21:12-13; cf. Acts 24:7-10, 24-25; 25:9-13; 26:1). Moreover, their testimony would not be theirs, though it came from their mouths. Rather, Jesus, himself, would give them the words they needed to say, and once said, their enemies wouldn’t be able to legitimately argue against them (Luke 21:14-15; cf. Acts 25:9-12, 23-26; 26:32).
