Paul’s testimony in Acts 22 was more 25 years after his conversion. But he had never lost his zeal. Acts 22 was supposed a defense opportunity for Paul but he used this as a testimony time. He worried not about his safety but whether he finished what God has called him to do. Consider he had already gone for 3 missionary journeys, he could probably retired. But he wanted to go the end of the world to share the gospel (This desire is recorded in Ro 15-16).
