The Underlying Principle of Holiness
God has always demanded holiness of those who would approach Him. The reason is clear--He is holy. Thus, those who would come into His presence and have fellowship with Him must be holy (Heb. 12:14; Rev. 21:27; 1 John 1:6-10). The apostle Peter penned these words: “But as he which hath called you is holy, so be ye holy in all manner of conversation; Because it is written, Be ye holy; for I am holy” (1 Pet. 1:15-16).
