The Greek word *hagiasmos* (G38), translated as holiness or sanctification, signifies separation and the condition produced by receiving God's Holy Spirit, as well as the behavior fitting those so separated. Derived from the verb *hagiazo*, meaning to make clean, it conveys the idea of rendering pure in a moral sense and purifying through consecration and devotion. This purification sets individuals apart from the world, marking them as distinct through the process of becoming clean. Sanctification, as represented by *hagiasmos*, is a critical step in God's plan, distinct from justification and salvation. It is the process of becoming holy, transforming into the image of Christ through daily living by God's laws with the aid of His Spirit. Without pursuing holiness, one cannot see God, emphasizing its essential role in preparing for the Kingdom of God. This journey of sanctification involves a lifelong commitment to purifying the mind and heart, aligning one's thoughts and actions with God's Word to reflect His nature.

After making the covenant with God, we must shift our focus to striving for sinlessness. Sinlessness, expressed with beauty, is the highest, greatest glory a human can attain. Its purpose is to give witness to the glory of God as shown in our lives and to add our small part in working with God to build godly character in us. Considering what we are in comparison to Him, we need all the time it takes to be sanctified completely and become holy as He is.

Sanctification, known as *hagiasmos* (G38) in New Testament Greek, encompasses three essential aspects: consecration, separation, and purification. Consecration is a condition where God declares something holy by His authority, setting it apart for His purpose, as seen with the vessels in the Temple. Separation, also a condition, distinguishes what is holy from what is common or profane, marking a clear division by God's decree. Purification, however, is a process that unfolds over time, especially in relation to people, due to human free will and the inherent carnal nature. While God can cover us with another's righteousness, true purification requires a gradual transformation, as we are not changed overnight. These concepts fall under the broader umbrella of holiness. According to Vines Expository Dictionary of Biblical Words, sanctification involves separation to God and a course of life that befits those so separated. This means that those initially set apart as holy by God are expected to live in a manner that produces purification, growing in righteousness over the course of their lives. God intends for His people to actively participate in this process, pursuing holiness with zeal and determination, as it is integral to their walk and to pleasing Him.

The English term sanctification is translated from the Greek term *hagiasmos* (G38), which simply means away from, setting apart, or separation. Basically, *hagiasmos* indicates a spiritual movement of conduct and attitude from one state or quality of life into another. Applied to Biblical usage, it signifies a movement of heart, mind, attitude, and conduct away from carnal worldliness and into godly holiness as a way of life. Sanctification absolutely will not occur in our life unless we cooperate with God. If we are cooperating with Him willingly and throwing ourselves into it, we will do what He says, and that is exactly what we need to do. God must see and witness that we are actually applying His words, as He is looking to see if we are truly applying them.

Sanctification, derived from the Greek term hagiasmos (G38), signifies a separation or movement away from one state of life to another. It reflects a spiritual shift in conduct and attitude, moving from carnal worldliness—embodied by satan, the world, and our own flesh—toward godly holiness, motivated by God's Holy Spirit as a new way of life. This process of sanctification demands active cooperation with Almighty God; it will not occur in our lives unless we willingly engage and commit to following His guidance. God desires to witness our application of His words, observing our efforts to align with His instructions as we progress in this transformative journey.

The concept of hagiasmos (G38) is central to understanding sanctification, which indicates a setting apart or separation, as well as the purpose for which one is set apart. In I Thessalonians 4:1-7, this Greek term appears three times, translated as both sanctification and holiness, reflecting not only the act of separation but also the divine connection and purity of conduct that God desires. Hagiasmos suggests both the process of being set apart and the reason for it, which is to achieve holiness, aligning with God's absolute purity. This dual meaning emphasizes that sanctification is more than a physical or external separation; it involves an internal transformation of character and attitude. The purpose of hagiasmos is twofold: to cease doing evil, as one did while in spiritual Egypt, and to learn to do well, preparing attitudes and conducts necessary for the Kingdom of God. This spiritual process, reflected in the Days of Unleavened Bread, underscores that sanctification is a lifelong journey, not a momentary act. It requires continuous effort to move further from the world, as God has willed, mirroring the Israelites' forty-year wilderness journey where internal separation was as critical as physical separation. Thus, hagiasmos encapsulates both the act of being set apart and the ongoing pursuit of holiness, driven by God's love and purpose for those He has called.

Sanctification, represented by the Greek term hagiasmos (G38), holds profound significance in the spiritual journey of the church. In common Greek usage, hagiasmos simply means being set apart or separated from others, as could be illustrated by Israel's exodus from Egypt if the Old Testament were written in Greek. However, in the New Covenant writings of the apostles, this term is used more expansively and specifically, encompassing a purposeful spiritual application. The apostles employed hagiasmos in three interconnected ways. First, it indicates the state of being called and set apart by God's actions, reflecting its most common Greek usage. Second, it signifies a continuing, dynamic process initiated by God's calling, suggesting constant movement toward a definite goal, much like Israel's journey through the wilderness. Third, it identifies the ultimate end result of God's work, which is absolute holiness and divine purity in every facet of life. Thus, understanding hagiasmos requires careful attention to the context in which it appears, as it encapsulates the entire spiritual journey through our own wilderness. In I Peter 1:2-3, sanctification is linked to the foreknowledge of God the Father and the work of the Spirit, leading to obedience and the sprinkling of the blood of Jesus Christ. By I Peter 1:13-16, the call to holiness is explicit, urging believers to be holy in all conduct as He who called them is holy. Further, in I Peter 2:9-10, the church is described as a chosen generation and a holy nation, set apart to proclaim the praises of Him who called them out of darkness into His marvelous light. This progression from being called to becoming holy underscores the dominant theme of sanctification throughout the epistle, highlighting the honor bestowed upon the few who are set apart by God out of billions. Sanctification begins beyond our control, not through anything earned, but as a gift from God. To make this practical in daily life, we must value this calling as a treasure of such worth that we strive not to lose any part of it. Our responsibility, as seen in Deuteronomy 7, is to respond to God's calling by keeping His commandments, statutes, and judgments. This process of sanctification places the onus on us to build appreciation for what we have been given and to remain loyal to God, ensuring constant movement toward holiness.

The concept of hagiasmos (G38) is central to the process of spiritual growth and transformation. In the Bible, this term is represented by both "sanctification" and "holiness," reflecting nuanced aspects of the same idea. Sanctification emphasizes being set apart for a specific divine purpose, while holiness draws attention to purity and cleanliness, mirroring God's own nature. We are called to be sanctified unto holiness, striving for a purity of character that aligns with God's image. This dual usage highlights the journey of becoming pure as He is pure, a critical aspect of conforming to the likeness of Christ.

The term hagiasmos (G38) refers to sanctification, which signifies a separation or a setting apart for holy use or purpose. This process is continual, beginning once a person is set apart and leading toward ultimate salvation. Salvation, in this context, involves the transformation from mortal to immortal, from material to spiritual composition, from human to divine. As stated, God has chosen individuals to salvation through sanctification of the Spirit, as seen in II Thessalonians 2:13. Additionally, believers are described as elect through sanctification of the Spirit unto obedience, according to I Peter 1:2. This ongoing process of sanctification, empowered by the Holy Spirit, is essential for the journey toward eternal life.

The concept of hagiasmos (G38), often understood as sanctification, ties directly into the core message of Proverbs 14:12, which warns that a way may seem right to a man, but its end is the way of death. This process of being set apart for God's purpose is reflected in the journey of salvation, where one must follow His instruction to avoid the pitfalls of carnal desires and prideful choices. The path of hagiasmos requires adherence to divine counsel, contrasting with the human tendency to pursue what appears straight or right but leads to destruction. Just as Proverbs emphasizes the need to heed wisdom to escape the snares of death, hagiasmos involves a transformative process, aligning one's life with God's truth to achieve the ultimate success He intends.
