“Be ye holy, as I am holy” The doctrine of separation is rooted and founded in the nature of a holy God. Specifically, personal separation from the world is referenced in I Peter 1:15-16. In studying out separation again, I am brought back to God’s character and nature and my response to Him. A proper understanding of God is necessary for me to fear Him. (Psalm 119:120; Isa 66:5) Those who know God best, fear Him most. Rev. 15:4 says, “Who shall not fear thee, O Lord and glorify thy name?” I read somewhere the following statement, “I think heaven wonders at those who do not fear him.” If I am to properly separate from the world, I must fear Him. And if I am to properly fear Him, I must understand that He is a holy God.
