Day 3: For us to be holy is to be set apart by God for God. God's holiness means that he is pure, perfect, right in all he is and does. He is the fully "set apart one." That means he is not part of the universe he stands above and beyond it. This totally holy God who is "transcendent" (beyond everything) has become "God with us" in Jesus. The word that describes this is "immanent". It is a word that means "right here" or "present." Ponder the "transcendence" and the "immanence" of God. It will take some mental effort…but it will be worth the effort.
Day 3: Christ, the holy sacrifice, has given his life so that you might be declared right with God. Now it is your privilege to live your life fully for him. What is in your life right now that is not "holy"? What needs to be "cut away" because it is not helping you know and love God and love others? See all that is not holy as a barrier to the greatest good in your life. Repent of it, learn to hate what is not holy.
