Take the Helmet of Salvation

And take the helmet of salvation ^{Eph. 6:17a KJV} 

Still reflecting on the armor of God we are commanded to put, to enable us to be strong in the Lord and in the power of His might; we must take the helmet of salvation. ^{1Th. 5:8} One of the different phases of salvation is repentance which means our minds must be renewed; ^{Mt. 3:2; 4:17; Lk. 13:1-5; 24:47; Acts 2:38; 3:19; 10:43; 2 Cor. 7:9-10; 1 Jn. 1:9} which means we must have a change of mind, a new way of thinking:

And be renewed in the spirit of your mind  ^{Eph. 4:23 KJV}

To be renewed, the Greek word ananeoo (G365) means the whole course of life now flows in a different direction, ^{2Cor. 5:17-18} to be renewed in the attitude of your mind by renouncing its vanity, ^{Eph. 4:17}  its darkness and blindness ^{Eph. 4:18} and learning of Christ. ^{Eph. 4:20-21}

And be not conformed to this world: but be ye transformed by the renewing of your mind, that you may prove what is that good, and acceptable, and perfect, will of God. ^{Rom. 12:2 KJV}

To be transformed is the Greek word metamorphoo (G3339) that means to be transformed or transfigured by a supernatural change. ^{2Cor. 3:18} This change is by a renewing of the mind or spirit: ^{Tit. 3:5; 2Cor. 4:16}

And have put on the new man, which is renewed in knowledge after the image of Him that created him. ^{Col. 3:10 KJV}

The Word of God is clear when it states that we must cast down imaginations, and every high thing that exalt itself against the knowledge of God, and bring into captivity every thought to the obedience of Christ. ^{2Cor. 10:5}  The only way to change our way of thinking is by thinking on that which we are commanded in the Word – to think as God thinks, we have to consider every thought we allow in our minds and think upon whatsoever things are true, honest, just, pure, lovely, are of good report; if there be any virtue, and if there be any praise, we have to think on these things. ^{Php. 4:8}

Let the wicked forsake his way, and the unrighteous man his thoughts: and let him return unto the LORD, and he will have mercy upon him; and to our God, for he will abundantly pardon. ^{Isa. 55:7 KJV}
