Sanctification, as revealed in the Bible, denotes the state, condition, and process of being separated from others for God's purposes. It is both a result of God's calling and an active, ongoing process that becomes increasingly refined over time. The basic meaning of sanctify is to set apart or separate, akin to a rancher cutting an animal away from the herd for a specific use. In the context of Israel's history, God sanctified the Israelites by calling them out of Egypt, distinguishing them from the uncalled Egyptians and other nations they encountered, such as the Moabites, Ammonites, and Canaanites, on their journey to the Promised Land. This separation was not by their own works but by God's sovereign choice and acts of grace, setting them apart for His special purpose as a holy, distinct people. God's acts of sanctification began with individuals like Enoch, Noah, and Abraham, whom He separated for specific purposes, laying the foundation for a family and nation through which He would work. With Israel, this sanctification was geographical, moving them from one place to another to establish a new community aligned with His purpose. God called Israel His son, drawing them out of Egypt through miraculous interventions, demonstrating that it was His doing that enabled their separation and journey. This pattern of setting apart continued as God made stringent demands on the Israelites, emphasizing their status as a sanctified, special people chosen out of all available nations, not because they were greater or better, but due to His love and choice. The responsibility of this sanctification for Israel was to keep His commandments, statutes, and judgments, thereby witnessing that their God is the Creator. This act of obedience served a dual purpose: it provided a witness to the world and allowed God to shape them into the design He intended. Even though Israel initially rejected the priesthood aspect of their calling due to fear and self-concern, failing to draw near to God as He desired, they retained a consciousness of representing Him before the world. To support this responsibility, God appointed Moses as their mediator and the family of Levi, specifically Aaron's family, to serve as priests, drawing near to Him and assisting in teaching the Israelites how to perform their witnessing role. Thus, Israel's sanctification established them as a holy people set apart to reflect God's purpose and presence among the nations.
