Why is sanctification important in our relationship with God?

Sanctification is the process of being made holy, which is essential for maintaining a right relationship with God. In Numbers 20:12, God admonishes Moses and Aaron for failing to sanctify Him before the people, indicating that our actions and words should reflect His holiness. This sanctification not only honors God but also serves as a powerful witness to those around us of His glory and character. As believers, we are called to lift up the name of Christ and honor His sacrifice, recognizing that glorifying God is central to our purpose and calling.
