Luke tells us something chilling: “Then Satan entered into Judas called Iscariot, who was of the number of the twelve.” Judas was not an outsider; he was one of the twelve, chosen, trained, and entrusted by Jesus Himself. For three years he walked with Christ, heard His teaching, watched miracles, and handled the money bag for the group. Yet in this moment, we are shown that the schemes at work are not only human—Satan himself is plotting, whispering, pushing toward betrayal. This reminds us that behind some of the most painful sins and betrayals in life, there is a spiritual enemy, not just flawed people making bad decisions. Scripture is soberly honest: we wrestle not merely with flesh and blood, but with the powers of darkness that hate Jesus and oppose His work in us.
Luke’s Gospel also connects this moment with an earlier one: after Satan finished tempting Jesus in the wilderness, he left Him “until an opportune time” (Luke 4:13). That “opportune time” comes into view here, as the devil looks for a doorway through a disciple’s divided heart. Judas did not go from devoted follower to betrayer overnight; small compromises, hidden greed, and unconfessed sin had been weakening his soul. When the moment came, Satan did not create Judas’s desires from nothing, but seized upon what had been quietly growing in the dark. The schemes of hell so often ride on the rails of our unchecked habits, resentments, and secret idols. This scene urges us to take seriously the slow drift of our hearts and bring them regularly into the light of Christ.
Still, this is not a story of Satan suddenly becoming stronger than Jesus; even here, God’s sovereign plan is being fulfilled through human choices and demonic malice. Jesus knew what Judas would do, and yet He washed Judas’s feet and shared bread with him, moving steadily toward the cross where He would conquer sin, death, and the devil. At the very moment Satan thought he was winning—turning a close friend into a traitor—God was weaving salvation for all who would trust in Christ. This means that even the betrayals and heartbreaks that Satan would use to ruin you can, in Christ’s hands, become instruments of deeper redemption and healing. The cross stands as proof that darkness does its worst and still cannot overturn the purposes of God. Where the enemy plots destruction, Jesus is quietly working deliverance.
For us, Judas’s story is both a warning and a mercy. It warns us not to presume on our nearness to spiritual things—church involvement, Christian service, and religious knowledge are not the same as a surrendered, guarded heart. We are called to watch and pray, to confess sin quickly, to name temptations honestly, and to lean on Christ’s strength rather than our own. At the same time, it is mercy, because it tells us that Jesus understands betrayal from the inside; He knows what it is to be wounded by those closest to Him. When you feel assailed by the schemes of people or the schemes of the devil, you are not abandoned—the crucified and risen Lord stands with you, able to keep you from falling. Take courage today: the One who saw Satan enter Judas is the same Savior who now intercedes for you and will hold you fast to the end.
