God is inescapable There is no place we can hide from Him. Not only does He penetrate every aspect of our lives, but He penetrates it in his majestic holiness. Therefore we must seek to understand what the holy is. We dare not seek to avoid it. There can be no worship, no spiritual growth, no true obedience without it. It defies our goal as Christians. God has declared, “Be holy, because I am holy.” (Leviticus 11:45). To reach that goal, we must understand what Holiness is.
