Romans 12:2 And do not be conformed to this world, but be transformed by the renewing of your mind, so that you may prove what is that good and acceptable and perfect will of God.
The high priest of Ancient Israel wore a crown of pure gold on his head called a Nezer, which comes from the word “nazar”. This word "nazar" means to dedicate, consecrate and sacredly separate. The word “nazarite” comes from this root, and describes someone who has taken a vow to be separated from the world.
New Covenant believers are called "a royal priesthood" [1 Peter 2:9], and we also, are called to live a holy life, dedicated to God and separated from the world in our thoughts and intentions. It's not always an easy task. Our thought life is constantly challenged from within and without. In this battle, the crown of the high priest can be a powerful symbol for us; the beauty and purity of gold standing for the beauty and purity of thinking with the mind of Messiah. Since Yeshua (Jesus) was the perfect "Nazarite", set apart in absolute purity, His thoughts were always "golden". In communion with Him by His spirit, our thought life too, can move more and more toward His perfect mind.
Philippians 4:8 says this; " Finally, brothers, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable-if anything is excellent or praiseworthy-think about such things. " This, as believers, is our mandate to "positive thinking". In this world, negativity, cynicism and impurity abound, and it becomes easier and easier to dwell on things that are depressing and sinful, impure and evil. But these thoughts must be cut off and destroyed from our minds. Thoughts of lust, jealously, covetousness, and self-pity will take us away from our Lord, and need to be taken captive before they get a foothold. Replace them with those of Philippians 4:8.
You have the mind of Messiah [1 Cor. 2:16] Choose to know and think with it. Crown yourself with thoughts that are pure as gold by taking control of that ceaseless flow. You'll be amazed at how your life will change under the influence of Yeshua's mind!
