In speaking of the Lord's Prayer and hallowing God's name, R.C. Sproul says
"God's kingdom will never come where His name is not hallowed. ... It is foolish to look for the kingdom anywhere God is not revered.
"The Bible never says that God is love, love, love, or mercy, mercy, mercy, or wrath, wrath, wrath, or justice, justice, justice. It does say that He is holy, holy, holy, the whole earth is full of His glory." (Sproul, The Holiness of God, pp. 25, 40).
Sometimes we focus on the horizontal dimension of faith, to demonstrate love, mercy, or even wrath and justice to other men. But proper inter-personal relations depend upon proper vertical perspective.
That is, we can't properly love, display mercy to, or exercise justice about our neighbor until we grasp the need to consider God's holiness.
