The concept of holiness as purity is central to understanding the nature of God and our relationship with Him. Holiness, derived from a root meaning to cut apart or separate, signifies being other and different, carrying strong implications of purity in character and morality. It indicates freedom from every stain, being immaculate in every detail, and separated from anything sinful, evil, dirty, or imperfect. When applied to God, holiness implies a cut above, a transcendent superiority, exceeding usual limits. God is above and beyond us, with an infinite distance separating Him from us in every quality, defined by absolute, unrivaled, unparalleled, and incomparable purity in every aspect of His being and actions. Holiness is not merely another characteristic of God but adds a transcendent quality to all His attributes. His love is holy love, His mercy is holy mercy, and His justice is holy justice. God lives according to principle, not whim or emotion, judging without prejudice and always acting with holy intent. This purity is evident in His judgments, as seen in the swift and severe reactions to profanation, such as with Nadab and Abihu, who offered profane fire and were consumed by fire from the Lord, demonstrating that God must be regarded as holy by those who come near Him. For us, as those called by God, holiness begins with being separated from the crowd, sanctified by Him for His use. This initial sanctification positions us as holy brethren, not yet reflecting the quality of character but a state of being set apart. However, holiness must be perfected through choices and attitudes leading to right conduct. We are called to cleanse ourselves from all filthiness of the flesh and spirit, perfecting holiness in the fear of God. This process involves separation from the profane, which means being far from the holy place, and striving to produce the divine likeness in all behavior. Purity is inherent in the concept of holiness, and whatsoever is holy must be treated with deference because of its relationship to God. We are to treat each other with kindness, meekness, humility, forbearance, and deference, recognizing that each has been separated to purity by God. The Holy Spirit is essential in this transformation, as only through God's Spirit can we possess His holiness. Without it, we cannot appreciate or attain the beauty of holiness, being repelled by it due to our carnal nature. Sanctification unto holiness begins with exposure to truth, as Jesus said, "Sanctify them by Your truth. Your word is truth." God's Word penetrates, cuts, and reveals falsehoods and deceptions in our minds, confronting us with choices to reject carnality and obey. Through this cleansing process, by the water of the Word and the Spirit of the Lord, we are transformed into His image, from glory to glory, striving to remove sin from our lives to see the Lord, for without holiness, no one will see Him. Holiness, as the beauty of all God's attributes, is the rule of His actions and the excellency of His divine nature, which we are bidden to emulate in all manner of conduct.

Holiness as purity centers on the command to be holy because God Himself is holy, a directive first given to ancient Israel in Leviticus and repeated for the Israel of God today in 1 Peter. This holiness is understood at its core as moral purity, a standard that encompasses all conduct and thought while leaving little room for useless endeavors or pointless thinking. The pursuit requires setting the mind on things above rather than on earthly matters, thereby aligning daily choices with the development of godly character and virtues such as honesty. Freedom from the bondage of sin, secured through the grace and truth that came by Jesus Christ, enables this growth in righteousness and allows believers to abide in His word and bear fruit. Moral purity is not achieved independently but through yielding to the Potter's work, exercising the virtues bestowed by the Spirit, and making deliberate choices that reject evil and worldly distractions. The Bride of Christ participates actively in this process, making herself ready by shunning sin and pursuing the likeness of the Father and the Son so that she may be prepared at the appointed time. Law keeping supports this purity, since transgression of the moral law constitutes sin and places every person under judgment, yet justification through Jesus Christ declares believers clean and separates them as a holy priesthood and chosen nation. Those who seek the Kingdom therefore remain vigilant against the cares of the world that choke spiritual growth, instead welcoming God's chastisements and the limits He places on human choices in order to fulfill His creative purpose of forming many sons and daughters into His holy image.
