TMK 308.3
(That I May Know Him 308.3)
The Lord Himself has established a separating wall between the things of the world and the things which He has chosen out of the world and sanctified to Himself. The world will not acknowledge this distinction.... But God has made this separation, and He will have it exist. In both the Old and the New Testaments the Lord has positively enjoined upon His people to be distinct from the world, in spirit, in pursuits, in practice; to be a holy nation, a peculiar people, that they may show forth the praises of Him who hath called them out of darkness into His marvelous light. The east is not farther from the west than are the children of light, in customs, practices, and spirit, from the children of darkness. This distinction will be more marked, more decided, as we near the close of time.... (TMK 308.3) MC VC
