John 13:27

That the devil did ever so enter into Judas as to possess him, as we read of many who were possessed, and violently acted by the devil, is more than we read and, where in holy writ: the entrance into him, signifies Judas's free and willing giving up of himself to the devil's suggestions and conduct; and in this sense the devil also before this time was entered into Judas, Luke 22:3. But as holy men are said to be filled with the Spirit of God, who had before received the Spirit, because the Holy Spirit came after upon them with fuller and stronger impulses and motions; so though the devil had formerly been moving Judas to this vile act, and had had his consent to it, yet after he had taken this mouthful, the devil plied him with stronger motions, impulses, and suggestions: and now he had mastered his conscience, and hardened his heart, so as he was more prepared for the villany about which he had some thoughts before. He had now, with an unbelieving and unthankful heart, been eating the passover, which was a type of Christ; and had so mastered his conscience, as to come and do this, with a vile heart, reeking before with treacherous and bloody designs against his Lord and Master. See what is the effect. His heart is more vile, more treacherous, and bloody; he is twice more the servant of the devil than he was before. The sop given him by Christ was but an accidental occasion of it; as the devil took more advantage from his now hardened and further emboldened heart, and he is twice more the child of the devil than he was before. Christ, knowing this, doth not command, advise, or exhort him; but, in a detestation, bids him go and do what he was resolved to do, and which he knew would be quickly; letting him know both that he knew what was in his heart, and that he was now ready to receive the effects of his malice.
