Holiness, as defined in the Scriptures, signifies being set apart, a cut above, separated for God's use. The first mention of holiness appears when God declared the ground holy in the presence of Moses at the burning bush, indicating that His presence sanctifies and sets apart. Similarly, the Sabbath was sanctified by God, made a cut above other days for His purpose, serving as a sign between Him and His people, as stated in Ezekiel 20:12, to show that He is the Lord who makes them holy. God calls His people to be holy, as He is holy, according to I Peter 1:15-16, emphasizing a separation not just physically but spiritually and morally, reflecting His character. This call to holiness is exemplified in Abraham, whom God separated from his family, making a covenant with him to be a father of many nations, as seen in Genesis 12:1-3 and 17:1-7. Abraham's faithfulness and obedience demonstrated his holiness, walking blameless before God. Likewise, God chose Israel to be a holy nation, a special treasure above all peoples, as noted in Deuteronomy 14:2 and Exodus 19:5, to represent Him and live obediently as a light to other nations. This same call extends to us today, chosen to be holy, set apart as a royal priesthood and a holy nation, according to I Peter 2:9, to proclaim His praises and demonstrate His character through our conduct. Holiness involves a process of sanctification and conversion, a daily striving to bear godly fruit and grow closer to Him. As Ephesians 1:3-6 reveals, God chose us before the foundation of the world to be holy and blameless before Him. Jesus Christ Himself reinforces this in John 15:16, stating that He chose and appointed us to bear lasting fruit. Thus, being holy is a command and a challenge, requiring us to live soberly, righteously, and godly, as urged in Titus 2:11-14, purified as His special people, zealous for good works.

The concept of holiness, as being set apart, is central to understanding God's call to His people. Holiness is rooted in the sacredness that comes from God's presence, as seen when Moses encountered the burning bush at Horeb. God declared the ground holy, instructing Moses to remove his sandals, for the place where he stood was made sacred by God's essence. This demonstrates that wherever God's presence dwells, that space is set apart and demands reverence. Similarly, Joshua, when in the presence of the Commander of the Lord's army, was commanded to take off his sandal, acknowledging the holiness of the ground. This repetition emphasizes that holiness is not a one-time event but a continual recognition of God's sacred nature. The priests, too, entered the Holy Place and the Holy of Holies barefoot, showing humility and respect as they approached what God had consecrated. The Sabbath day is another profound example of holiness as being set apart. God sanctified the seventh day, resting from His work and blessing it, making it distinct from the other days. Just as the ground was made holy by His presence, the Sabbath is a holy time, not to be treated as ordinary. God commands His people to remember the Sabbath, to keep it holy, refraining from regular work and honoring Him by treating it with respect. The Sabbath also serves as a sign between God and His people, a covenant marker that sets them apart. It facilitates a relationship with the Creator, necessary for spiritual understanding and eternal life. God warns against trampling the Sabbath, urging His people to delight in it and refrain from personal pursuits, treating it as sacred ground, much like Moses and Joshua did in His presence. This call to holiness extends to all aspects of life, as God Himself is holy and has set apart His people to reflect His sacred nature.
