Why is sweat significant in understanding our need for Christ?

Sweat is significant as it symbolizes the consequences of sin introduced in Genesis 3 when God declared that man would eat by the sweat of his brow due to the fall. In the context of the Old Testament priests, who were forbidden to wear wool in the temple because it would cause sweat, we see a representation of man's rebellion against God. Yet, Christ's sweat, especially as He prayed in Gethsemane, symbolizes the deep agony and the price He paid for our redemption. He bore the weight of our sin, sweat mingled with blood, fulfilling the law that we could not, and providing the righteousness needed to robed us before God.
