Holiness is the essential factor that brings true peace to our spiritual journey. Since peace comes from God's presence and God is holy, we must pursue holiness to experience His presence fully. Being holy means being separate and set apart, living out of God's holiness rather than our own righteousness. God promises to be with us, walk with us, and claim us as His children when we pursue holiness. This pursuit isn't about achieving perfection but about consecrating ourselves to God and surrendering areas that keep us from experiencing His presence fully.
