Separation means to disconnect or a parting of the ways. Are you parting from the ways of this world and from the ruler of this world?
“We are not to elevate our standard just a little above the world’s standard, but we are to make the distinction decidedly apparent. The reason we have had so little influence upon unbelieving relatives and associates is that there has been so little decided difference between our practices and those of the world.”
“Come out from among them, and be ye separate, saith the Lord, and touch not the unclean thing; and I will receive you, and will be a Father unto you, and ye shall be My sons and daughters, saith the Lord Almighty” [II Corinthians 6:17, 18]. These are the conditions upon which we may be acknowledged as the sons of God—separation from the world, and renunciation of those things which delude, and fascinate, and ensnare.
