John 13:27
And after the sop Satan entered into him. Then said Jesus unto him, That thou doest, do quickly.
John 13:27 (KJV)
Context
This verse belongs to the Last Supper narrative, the final meal Jesus shared with His disciples before His crucifixion. Moments earlier, Jesus had washed the disciples’ feet as a lesson in humble service. He then identified His betrayer by dipping a piece of bread and handing it to Judas Iscariot.
The sequence matters. Judas had already resolved in his heart to betray Jesus. The sop, a piece or crust of bread dipped in the dish, was the sign Jesus gave to point out the betrayer. After Judas received it, the text says Satan entered into him. This is not a metaphor; the Gospel presents a direct satanic influence taking hold of Judas, filling his mind and stirring him to pursue his wicked plan with greater eagerness.
Meaning
Jesus’ words, “That thou doest, do quickly,” are not a command to sin. They are a sovereign acknowledgment that the betrayal is now set in motion. Jesus is not surprised or defeated. He is in control, moving deliberately toward the cross. His instruction carries urgency because the events leading to His crucifixion must unfold to fulfill God’s redemptive purpose.
The disciples did not understand what Jesus meant. Some thought He was telling Judas to buy what was needed for the feast or to give something to the poor. Jesus’ words were cryptic to the others, but Judas understood their import.
Application
This verse is a sobering reminder of the gravity of unrepentant sin. Judas had been warned, yet he continued on his path, and the door opened for Satan’s full influence. It also reveals the depth of Jesus’ submission to the Father’s plan. He does not hinder Judas or delay the inevitable; He allows events to proceed.
For believers, the verse exposes the reality of spiritual warfare and the consequences of yielding to sin. It also offers comfort: Christ’s sovereignty is not threatened by human betrayal. He uses even the treachery of a friend to accomplish redemption, turning the darkest moment into the means of salvation.
Reflection
Jesus faced betrayal without bitterness or resistance. His calm instruction to Judas shows a heart fully surrendered to the Father’s will. The same Savior who moved toward the cross for Judas’ sake moves toward us in our failures, inviting us to turn from sin before it hardens into something worse.
