T. Austin-Sparks emphasizes that the messenger must embody the message, using Ezekiel's three titles: 'Son of Man,' 'a watchman,' and 'I am your sign.' He explains that 'Son of Man' signifies God's original thought of man, while 'a watchman' denotes the responsibility to discern and declare God's timing and warnings. The title 'I am your sign' illustrates that the messenger's life must reflect the message they deliver, as seen in Ezekiel's experiences. Sparks stresses that true ministry arises from personal experience and transformation, making the messenger a living testament to God's truth. Ultimately, the church must express Christ as the corporate man, embodying His message in their lives.
