Holiness, as conduct, is a reflection of being set apart for God's purpose, a call to live a life distinct from our sinful nature and dedicated to Him. It is not merely about physical separation but involves a spiritual and moral transformation, striving to mirror God's character and qualities through the possession of His Holy Spirit. As seen with Abraham, holiness in conduct meant walking blameless before God, showing love, faithfulness, and devotion through actions. Abraham's life exemplified this by trusting God, stepping out in faith, and adhering to His statutes, becoming a friend of God through a reciprocal bond of shared interests and mutual care. God chose Israel to be His holy nation, calling them to live in obedience to His commandments and covenant, maintaining a distinct identity as His people by living uprightly and serving as a light to other nations. Though they often failed to take His covenant to heart, observing commands and rituals without true dedication, the expectation remained for loyalty to Him. Today, we are similarly called to be holy, set apart as a special treasure to the Lord, chosen to be a light and example to others through our conduct, demonstrating God's love and character in our daily interactions. Bearing godly fruit is a visible sign of a holy life, rooted in obedience to God and reflected in conduct toward Jesus Christ, showing love, patience, kindness, humility, and forgiveness. Becoming holy is a daunting challenge and a commanded process of sanctification and conversion, involving growth through trials to strengthen us toward perfection. Christ lives to make us holy, investing in us as His treasure, desiring us to be blameless and grow closer to complete righteousness. We must prepare mentally and spiritually for action, focusing our thoughts, eliminating distractions, and readying ourselves for spiritual challenges and resistance against temptation, as we are called to be holy, for He is holy.

God declares us holy under the blood of Christ and expects us to become holy through Christian growth. We are called to be holy in all our conduct, as it is written, "Be holy, for I am holy." This holiness is not achieved through a single act of faith, love, kindness, sacrifice, or generosity, but through consistent obedience to His ways. One sin, however, can make us unholy and may even cost us our lives. God is serious about what He has made holy, and when we ignore or trample on His holy things, we risk endangering our eternal life. By striving to become holy as He is holy, we magnify His great name through our faithfulness to Him and His way of life. If we allow God to use us, keeping His laws as He has commanded in all our conduct, we will be holy as He is holy.

Holiness as conduct is a central theme in the chapters of Leviticus often referred to as the holiness code, particularly in chapters 17 through 23. These chapters emphasize that because God is holy, His people must reflect His character in their daily lives through their thoughts, speech, and deeds. God repeatedly declares, "I am the Lord," as a reminder of His holiness and authority, instructing His people to act in ways that mirror His nature. The purpose of the numerous laws and statutes in these chapters is to teach how God lives, revealing His essential nature of ultimate purity and holiness. Since He commands His people to become holy as He is, they are to live according to these guidelines. However, holiness is not achieved merely by following these laws. Only God, who is inherently holy, has the power to sanctify and make something holy. A person cannot become holy simply by adhering to these rules; rather, God first sets them apart, and their conduct in keeping His laws is a response to being sanctified. This process begins with an initial declaration of holiness when one comes under God's covenant, followed by a lifelong journey of growing in holiness through His guidance. The laws serve as tools to help maintain and build holy character, but without God's active participation, one can at best be moral, not truly holy. The holiness code remains relevant as it reflects God's unchanging character, teaching how to grow in righteous, godly behavior. While some laws may no longer apply in their literal form due to changes in context, their spiritual principles endure and must be thoughtfully applied to current circumstances. The spirit of the law often extends beyond the letter, requiring meditation and discernment to understand how to live out God's will in daily actions. By striving to be like Christ, one becomes holier, more set apart, and more reflective of God's transcendent purity. Thus, the holiness code is a vital guide for conduct, helping God's people to remain holy and grow in His image.
