TEXT: JOHN 6:70-71; 13:2; 13:27; LUKE 22:3-6; 2CORINTHIANS 10:4-5; PROVERBS 23:7

John 13:2- And supper being ended, the devil having already put it into the heart of Judas Iscariot, Simon’s son, to betray Him

Luke 22:3-6- Then Satan entered Judas, surnamed Iscariot, who was numbered among the twelve. 4So he went his way and conferred with the chief priests and captains how he might betray Him to them. 5And they were glad and agreed to give him money. 6So he promised and sought opportunity to betray Him to them in the absence of the multitude.

Today’s word centers round Judas Iscariot and how he betrayed Jesus. Judas was the treasurer of the team of Jesus’ disciples. He held the money bag but he used to steal from it because he was a thief (John 12:6). However, Jesus knew all these and called him a devil (John 6:70-71). And how else could he prove that he was one if not by stealing (John 10:10) and lying (John 12:6; 8:44)? Apart from all the above, Judas was very careless with his heart. John 13:2 told us that the devil put the thought of killing Jesus into his heart long before he betrayed Christ. After the devil succeeded in putting the thought in his mind, he pondered on it over again till the point where he drafted out a plan of how he would execute all the things he thought about (Luke 22:6). Eventually, he carried out all that was in his heart concerning Jesus.

What is the lesson here? The scriptures say in Proverbs 4:23 ‘Keep your heart with ALL DILIGENCE, for out of it spring the issues of life.’ Because Judas failed to keep his heart with all diligence like the bible told us in the above verse, the devil was able to permeate to his thoughts; and those thoughts thrived in his heart until they became mature to be executed with a well organized plan. ALL DILIGENCE means you must do everything possible in your ability and with God’s help to keep your heart safe always. That instruction came in the scriptures because God knows that all manners of thoughts will definitely come into our minds. But as Spirit controlled beings we must be able to hold the lock and keys of our hearts and determine what goes in or out.

In order to guard our hearts with all diligence, 2 Corinthians 10:4-5 tells us that we fight battles, wars in our minds (i.e. the mind is our battlefield) not with physical weapons of war such as bombs, guns, arrows, spears, knives etc but we fight with weapons that the physical eyes cannot behold. We fight these battles with spiritual weapons that are mighty in God. These weapons

  1. Pull down strong holds
  2. Cast down arguments and everything that exalts itself against the knowledge of the Lord
  3. Bring thoughts into captivity to the obedience of Christ.

Wow! Has anyone seen such weapons before, weapons that are solely developed to help the human mind fight against negative and ungodly thoughts? Well, there may be drugs that can help to some extent in that regard, but they cannot take ungodly thoughts captive and make them obedient to Christ. They do have the ability to take some thoughts away but they do not have the ability to oppress those thoughts in the name of Jesus. It is only the man who knows Jesus, walks with Him closely, obeys His commands and abides in Him, who is controlled by His Spirit that can adequately access and use these spiritual weapons which are not canal.

Any man who is on the battle field ought to be properly dressed for that purpose. Therefore, on our battle field we must be dressed in the full armor of God like Ephesians 6:10-18 describes:

  • Belt of truth
  • Breast plate of righteousness
  • Shoes of propagation of the gospel of peace
  • Shield of faith
  • Helmet of salvation
  • Sword of the Spirit
  • Others are praying in the spirit and watchfulness.

Anyone who uses the above in fighting their battles will be victorious. All the above were lacking in Judas Iscariot, so instead of fighting the evil thought that came into his mind, he settled with it. He never knew that making peace with the devil was an invitation to a useless life and destiny.


Lord Jesus, I receive grace to guard my heart with all diligence and to be well dressed in the full armor of God so as to fight all these battles that face me daily in Jesus name.
