Jesus says the Spirit 'will not speak on his own authority,' but will speak 'whatever he hears.' This sounds like a subordinate, but it's actually a sign of perfect unity and divine authority.
The Spirit's complete reliance on what he 'hears' from the Father and the Son is a profound declaration of the Trinity's unity. It means the Spirit doesn't have an agenda separate from God's. He is not an independent entity creating new doctrines or pronouncements. Instead, he faithfully reveals God's will and truth, ensuring that everything he communicates is perfectly aligned with the divine counsel. As Calvin notes, this assures us that the Spirit's message is divine, not of this world. Furthermore, this 'hearing' and 'speaking' extends to 'the things that are to come.' This doesn't just mean predicting future events like earthquakes or elections; it refers to God's unfolding plan, the future realities of His kingdom, the completion of His work in Christ. The Spirit is our guide into understanding God's grand narrative, both now and into the future.
