Romans 12:1-2 (KJV)
I beseech you therefore, brethren, by the mercies of God, that ye present your bodies a living sacrifice, holy, acceptable unto God, which is your reasonable service. And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God.
When we come to Jesus, it is a process of presenting ourselves to Him, and by His ‘mercies’ be presented a ‘living sacrifice”, made “holy” by His blood washing away our sins, and thereby we become ‘acceptable unto God.’ This is “reasonable’ that we do this.
No longer do we want to be ‘conformed’ to this world and its ways. The world’s ways are sinful and an abomination in the sight of the One to Whom we have now been presented. Therefore, our minds need ‘renewed’ and made clean of all sin. This is a ‘transformation’ process that begins at salvation, and continues with that renewed mind now seeing all things different than before.
be not conformed to this world
The word ‘conformed is the Greek: suschematizo (G4964) meaning to conform to another's example. It is the ‘mind of Christ’ we are to ‘conform’ to, but too often people ‘conform’ to the ‘world’. The word for ‘world’ is the Greek word, aion (G165) meaning ‘age’. We are not to pattern after this age. We often hear people say things like ‘this is the 21st century, and we must adjust’, or others say ‘that is old fashioned thinking’ about verses in the Bible. The Bible is never outdated, God wrote it to be eternal, and it , just as valid and true in a million years as it is now. We need to find the ‘mind of Christ’ and not seek to think like the world.
Be ye transformed
The word ‘transformed’ is from the Greek word ‘metamorphoo’ (G3339), meaning ‘transformed or transfigured by a supernatural change.’ This refers to a supernatural miracle, doing what cannot be done without God’s power.
Paul exhorts believers to be transformed, rather than to be conformed to this world's ways. We are not to let the world put us into their mold, we are not to look in the spiritual mirror, and see the same thing that the world sees. We should see Jesus, when we look in that spiritual mirror. We should have a mind that thinks like His would if He were in our situation. Sin is still sin, murder is still evil, abortion is not suddenly righteous because society says that a woman can choose to murder the unborn, but only the born cannot be murdered at her choice. Cursing and using God’s name in vain is still as evil as they always were in past generations.
We are told to be "living sacrifices" (Romans 12:1) for God does not desire us to die for Him (though He sometimes allows us to die), but He certainly does want us to live for Him daily. If we conform to the world, we are not living for Him. If we are transformed to think as He does, then we will be living sacrifices for Him, for the world will hate us, treat us, as they treated Him.
Our "mind" is what needs ‘transformed’. Our thinking is warped by the world, lied to by the devil and his cohorts, and twisted by the cursed circumstances of life. The Greek word is ‘nous’ and means the "capacity to perceive." Our perceptions and thoughts need to be reshaped by God's presentation of truths shown in Scriptures.
We can then be totally in God's will. The word dokimazo, prove, means to be assured positively knowing God’s will. Paul is saying that we can trust God's will to be good, to be acceptable, to be perfect, for our life. We will be thinking aright, so we will easily understand God’s will.
If we can ‘think soberly’, we look at ourselves honestly, we can realize the needs of others, and we can be of use of the Lord being that ‘living sacrifice.’
Romans 12:9 (KJV)
Let love be without dissimulation. Abhor that which is evil; cleave to that which is good.
The transformed mind, the correct and Godly thinking, brings a ‘love’, and this love is for real. It causes the children of God to abhor evil, and cleave to good. To function well in one’s thinking, we must have this love from the thinking of the mind.
Love is not some conventional concept. Love is a way of thinking, it is an expression of the heart. The transformed thinking is based on love, is motivated by love, and judges all things with this love. Love is wonderful.
The ‘renewing’ of our mind is not a mere change of decision, but it is one which results from an entire alteration of the whole way of thinking, the whole nature of the being.
THE UN-RENEWED MIND
Some of the wicked have a ‘reprobate’ mind, guided by the loss of God in their heart, and doing things not wise due to that reprobate mind.
Romans 1:28 (KJV)
And even as they did not like to retain God in their knowledge, God gave them over to a reprobate mind, to do those things which are not convenient;
Many have an ‘alienation’ from God, which results in a vain, worthless mind, and gives them darkened understanding.
Ephesians 4:17-18 (KJV)
This I say therefore, and testify in the Lord, that ye henceforth walk not as other Gentiles walk, in the vanity of their mind, Having the understanding darkened, being alienated from the life of God through the ignorance that is in them, because of the blindness of their heart:
We must be renewed in our mind, by a renewal of having God rule and umpire our mind. This is a command, and a necessity to survive this wicked world.
Ephesians 4:23 (KJV)
And be renewed in the spirit of your mind;
When our thinking is aright, is transformed, we will then be able to ascertain, prove, what is that good and acceptable and perfect will of God. We are renewed in our thinking so we can approve and agree with what is God’s will and God’s thinking. That brings happy thinking.
Ephesians 5:8-10 (KJV)
For ye were sometimes darkness, but now are ye light in the Lord: walk as children of light: (For the fruit of the Spirit is in all goodness and righteousness and truth. Proving what is acceptable unto the Lord.
We should not be unwise in our thinking, we need a transformation, a renewal of our thinking, so we can know and can agree with the will of God.
Ephesians 5:17 (KJV)
Wherefore be ye not unwise, but understanding what the will of the Lord is.
SIN TRIES TO KEEP US IN BONDAGE TO UN-GODLIKE THINKING.
Sin grips with a hold that is unbreakable by most. It can become habitual and increase its grip. Sin is never satisfied. It will take more and more control. Sin will begin as a thought, and soon become an action. The action will develop into a habit. The habits will form one's character. The character will end in one reaping a destiny. Sin will kill. It is a moral cancer to the soul.
"When lust hath conceived, it bringeth forth sin, and when sin is finished, it brings forth death."
What is the answer? Only repentance to Jesus is the answer!
"But as many as received Him, to them gave He power to become the sons of God."
"If the Son therefore shall make you free, ye shall be free indeed."
We have a Savior that is able to wash our sins away, We may confess our sins to Him, and He will forgive us and cleanse us from all unrighteousness.
I John 1:9
"If we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness."
