What does the Bible say about Christ's presence?

The Bible emphasizes that Christ's presence is the key to the sanctification and separation of His people. In Exodus 33, we see Moses asking for God's presence, indicating that true separation from the world comes from having Christ with us. It is stated that without His presence, we cannot discern that we are truly His people. His presence not only sets us apart but also guides us in knowing His way, offering us rest and leading us through trials. Ultimately, it is the presence of Christ that sanctifies us and makes us holy in the sight of God.
