Why was Jesus silent during his trial?

Christ's silence during His trial and crucifixion is deeply significant and reflects fulfillment of prophecy, particularly as outlined in Isaiah 53:7, where it prophesies the Messiah being led like a sheep to the slaughter without opening His mouth. This silence was not born of weakness but was a deliberate act to embody the role of the substitute for our sins. As Gabe Stalnaker expounds, Jesus stood silently in place of sinners, allowing the justice of God to be satisfied through His suffering and death. By not defending Himself, He took upon our guilt and shame, offering us salvation through His sacrificial love, affirming that our salvation is rooted in His sufficiency and grace.
