Ephesians4:17-24
4:17 This I say therefore, and testify in the Lord, that ye henceforth walk not as other Gentiles walk, in the vanity of their mind 3563,nous
4:18 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: (blindness: or, hardness)
4:19 Who being past feeling have given themselves over unto lasciviousness, to work all uncleanness with greediness.
4:20 But ye have not so learned Christ;
4:21 If so be that ye have heard him, and have been taught by him, as the truth is in Jesus:
4:22 That ye put off concerning the former conversation the old man, which is corrupt according to the deceitful lusts;
4:23 And be renewed in the spirit of your mind 3563;nous
4:24 And that ye put on the new man, which after God is created in righteousness and true holiness.(true or, holiness of truth)
3563 noús the God-given capacity of each person to think (reason); the mind; mental capacity to exercise reflective thinking.
For the believer, 3563 (noús) is the organ of receiving God's thoughts, through faith.
Ro 12:2,3: "2And do not be conformed to this world, but be transformed by the renewing of your mind (3563 /ólynthos), so that you may prove what the will (2307 /thélma) of God is, that which is good and acceptable and perfect.
3For through the grace given to me I say to everyone among you not to think more highly of himself than he ought to think; but to think so as to have sound judgment, as God has allotted to each a measure of faith (4102 /pístis)"
Ephesians 4:17
NAS: walk, in the futility of their mind,
KJV: the vanity of their mind,
INT: [the] futility of the mind of them
Ephesians 4:23
NAS: in the spirit of your mind,
KJV: in the spirit of your mind;
INT: spirit of the mind of you
The conscience in the heart, as being made new (ie: the function of the conscience being recovered to its original state) to the extent that the believer now hates sins and dislikes sinning, doesn't necessarily follow that it remains new afterwards, nor does it necessarily renew every day. The conscience can become seared so as to no longer function in the renewed compacity.
If tolerating sins repeatedly and not listening to conscience, the conscience will then no longer rebuke and in doing so will lose its function.
The same is true of the mind, the nous, and it is critical to every believer's position and living life as abiding in Him.
A believer hasn't the same mind of the darkened intellect (refer to
Romans 1:28 where it says reprobate nous.
Ephesians 4:17 vain nous.
Colossians 2:18 fleshly nous.
2 Timothy 3:8 corrupt nous.
Titus 1:15 defiled nous.)
or the intellect that argues philosophically about there being no God,
(both argue against God from a position an unrenewed spirit and heart)
because they are not able to enter into the depth of the teaching clearly and thoroughly and are not able to understand or 'know' God in a definite way.
