Now to the mind. At the new birth our spirit is recreated and washed by the blood of Jesus to cleanse it from sin. But of the mind is relatively unchanged. We know and understand that we have been saved. But all the garbage and I do mean garbage of the world that filled our mind before we were saved is still very much apart of our mind after we are saved. With the renewing of the mind we will be reprogrammed to think according to the will of God. To love the Lord with all our mind we must do three things on an on going bases with our minds.
1) The first thing we must do with the mind is renew it by reprogramming it.
We must reprogram the mind to think according to the will of God, which is to transform the mind by the study of the Word of God.
(Rom 12:2 NKJV)
2 And do not be conformed to this world, but be transformed by the renewing of your mind, that you may prove what is that good and acceptable and perfect will of God.
As we renew the mind with the Word of God we must use the things we learn in the Word to control the way we think. We choose to think and pray the will of God as we find His will taught in the Word.
(Phil 4:4 – 8 NKJV)
4 Rejoice in the Lord always. Again I will say, rejoice! 5 Let your gentleness be known to all men. The Lord is at hand. 6 Be anxious for nothing, but in everything by prayer and supplication, with thanksgiving, let your requests be made known to God; 7 and the peace of God, which surpasses all understanding, will guard your hearts and minds through Christ Jesus. 8 Finally, brethren, whatever things are true, whatever things are noble, whatever things are just, whatever things are pure, whatever things are lovely, whatever things are of good report, if there is any virtue and if there is anything praiseworthy; meditate on these things.
(Eph 4:21 -29 NKJV)
21 if indeed you have heard Him and have been taught by Him, as the truth is in Jesus: 22 that you put off, concerning your former conduct, the old man which grows corrupt according to the deceitful lusts, 23 and be renewed in the spirit of your mind, 24 and that you put on the new man which was created according to God, in true righteousness and holiness. 25 Therefore, putting away lying, "Let each one of you speak truth with his neighbor," for we are members of one another. 26 "Be angry, and do not sin": do not let the sun go down on your wrath, 27 nor give place to the devil. 28 Let him who stole steal no longer, but rather let him labor, working with his hands what is good, that he may have something to give him who has need. 29 Let no corrupt word proceed out of your mouth, but what is good for necessary edification, that it may impart grace to the hearers.
2) The second thing that we must do with the mind is meditate on the Word that we put in our mind.
There is a major power that can be ours through filling the mind with the word and then meditating on the word in our minds day and night.
(Josh 1:7 - 9 NKJV)
(7) "Only be strong and very courageous, that you may observe to do according to all the law which Moses My servant commanded you; do not turn from it to the right hand or to the left, that you may prosper wherever you go. (8) "This Book of the Law shall not depart from your mouth, but you shall meditate in it day and night, that you may observe to do according to all that is written in it. For then you will make your way prosperous, and then you will have good success. (9) "Have I not commanded you? Be strong and of good courage; do not be afraid, nor be dismayed, for the LORD your God is with you wherever you go."
Controlling the thoughts of the mind is to willfully choose what we allow our minds to think about. Controlling the thoughts of the mind will include what we allow to enter our minds through the eyes and the ears. By controlling the input to the mind we are controlling the things that we allow the mind to thing about and then meditate on. A single though does not become a sin if not allowed to stay in the mind. A wrongful thought only becomes a sin when meditated on. This leads us to the third thing we must do with our minds.
3) The third and last thing that we must do on an ongoing bases is casting down arguments and every high thing that exalts itself against the knowledge of God which is the Word of God that is in our minds and that we meditate on.
The last thing that we must do with the mind is understand that we must cast down wrongful thoughts. Besides our own ability to wrongful meditation on things that were already apart of the mind when we were saved, we have to guard against allowing additional sinful thoughts to enter our minds through our eyes and hears. In our lives in today’s world, a great source of wrongful thinking and seeing can be found at any moment in time on the TV and at most ticket boxes. It is our choice moment by moment to choose to stop inappropriate thing that is either apart of our pass or comes in from the outside world.
An other source of wrongful thinking comes from satan.
(2 Cor 10:3 NKJV
3 For though we walk in the flesh, we do not war according to the flesh. 4 For the weapons of our warfare are not carnal but mighty in God for pulling down strongholds, 5 casting down arguments and every high thing that exalts itself against the knowledge of God, bringing every thought into captivity to the obedience of Christ,
satan has the ability to impose his plan on us through our minds or to put thought into our minds to confuse and misdirect us. We must constantly be on guard to put those thoughts out of our minds.
(2 Cor 4:3 NKJV)
3 But even if our gospel is veiled, it is veiled to those who are perishing, 4 whose minds the god of this age has blinded, who do not believe, lest the light of the gospel of the glory of Christ, who is the image of God, should shine on them.
As we fill our hearts and minds with the Word of God, our prayer and supplication will be guided by the Word. The power of that Word in us will keep our hearts and our minds in Christ Jesus
(Phil 4:6 – 7 NKJV)
(6) Be anxious for nothing, but in everything by prayer and supplication, with thanksgiving, let your requests be made known to God; (:7) and the peace of God, which surpasses all understanding, will guard your hearts and minds through Christ Jesus.
