Satan, the chief liar and father of all liars is also a thief.   He comes to steal.   Believers are able to see how he steals life from those in bondage to him.   

But believers are not immune to his lying and stealing.   Jesus repeatedly emphasized:
   → knowing the Truth Joh 8:32
   → being set free Joh 8:36
   → having faith Mar 9:23

Satan does not want us to grasp these fundamental teachings of Christ because he knows the power that is in them.   

How many believers have fully received the Truth?   

How many believers are Free Indeed?   

How many believers literally believe what Jesus said?   

To get at the answers to these questions we must know what is implied by each of the terms, Truth, Free Indeed and Believe.   

Jesus is the Truth about what we refer to as 'God'.   But He is also the Truth about us and our potential, particularly in the New Birth.   

Free Indeed is being completely unfettered, not only from sin, but from the principalities in High Places - ideas, opinions, policies implementing social and political pressure.   
Furthermore, it is being free from the opinions of other believers.   

Believing the Word Of The Lord to the extent that we speak it and do it is how we manifest our Faith in the Lord.   

One of the most amazing statements in the Bible was not spoken directly by Christ Jesus but by His Holy Spirit through the apostle Paul:

Let this mind be in you, which was also in Christ Jesus: Phi 2:5 Jesus wants us to be like Him.     After all, He created us in His image Gen 1:26.      He chided His disciples when they did not measure up to their potential.     'Oh you of litte faith, why are you so fearful' Mar 4:40.      Jesus made it possible for us to be accepted by the Holy Spirit through His blood sacrifice Eph 1:6.      Once cleansed He made it possible for us to receive the Holy Spirit Luk 24:49.      That Holy Spirit is who raised Christ Jesus from the dead Rom 8:11.      He told us that greater deeds would we do as a result of receiving that gift Joh 14:12.      But, in order for us to realize our potential we must 'realize our potential' 1Jn 3:2.      As we think in our hearts so are we Pro 23:7.      For me or you to reach our potential in Christ we must believe what He said about us to the extent that we allow it to transform our thoughts, words and deeds Rom 12:2.      The Mind Of Christ is achieved by knowingly and willingly being transformed by the Word and Holy Spirit Phi 2:5.      We must desire to have the Mind Of Christ and we must feed on what He fed on to arrive at the same place He did Mat 5:6.      Jesus said the Kingdom Of Heaven is at hand when He walked the earth Mat 4:17.      In the Word and Holy Spirit we can manifest heaven on earth Mat 12:28.      It is His will but is it yours?     Eph 3:20

Who, being the image of the Holy Spirit, thought it not robbery to be equal with the HolySpirit: Phi 2:6 What is the form of our Creator?      We need only look at man who was made in His image Gen 1:26.      The Holy Spirit formed Jesus in Mary's womb for the purpose of manifesting Himself in the body of Jesus.      Since the Holy Spirit did this, Jesus did not think it presumptuous for Him to be equal with the Holy Spirit.      It is this thinking in His mind and heart that enabled Him to speak the words of the Holy Spirit and by the power of the Holy Spirit to do the works of the Holy Spirit - just as He had done in the beginning when He created all things.

But made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men: Phi 2:7 But Jesus did not lift Himself up.     He lifted the Father up and glorified Him.     Jesus humbled His soul's will to the will of His Holy Spirit.      We must humble our soul's will to the will of our New Spirit in order to manifest as a Son Of The Holy Spirit.

And being found in fashion as a man, he humbled himself, and became obedient unto death, even the death of the cross. Phi 2:8 Jesus was obedient to His Holy Spirit.      Jesus' humility brought complete and utter obedience into His heart such that even death did not deter Him.

Wherefore the Father also has highly exalted him, and given him a name which is above every name: Phi 2:9 Jesus' perfect performance of the will of His Holy Spirit brought honour and glory to Him such that the name of Jesus is exalted above every name.

That at the name of Jesus every knee should bow, of things in heaven, and things in earth, and things under the earth; Phi 2:10 One of these days every knee will bow to Jesus including all those who have received Him as well as all those who have rejected Him.

And that every tongue should confess that Jesus Christ is Lord, to the glory of the Holy Spirit Father. Phi 2:11 All humanity will speak in confession that Jesus is Lord and thus glorify the Father whose plan He fulfilled.      Who is the Father?     Holy Spirit.      It was the Holy Spirit that impregnated Mary.     It was the Holy Spirit that was in Jesus empowering Him to speak and do His will.      Jesus said if you have seen me you have seen the Father.         → Jesus is the body of the Holy Spirit.         → The Holy Spirit is the Spirit Of Christ Jesus.

Wherefore, my beloved, as you have always obeyed, not as in my presence only, but now much more in my absence, work out your own salvation with fear and trembling. Phi 2:12 Paul is speaking to Soul Salvation which enables us to experience Abundant Life in the soul and body and to be effective witnesses of Christ Jesus.         → Soul Salvation must be worked out by us.         → Spirit Salvation is the gift of the Holy Spirit by faith In Christ Jesus.

Not only is it is not presumptuous of a believer to have the Mind Of Christ, but we are commanded to have it.   We can exercise no effective authority or power by ourselves.   It is by the Word and Holy Spirit of Christ Jesus that we will be effective for the Kingdom.
