The Greek word is used for different things, as follows: In Matt. 25:34; John 17:5; Acts 17:24; Eph. 1:4 and Rev. 13:8, it denotes the material universe as a system created by God. In John 1:29; 3:16 and Rom. 5:12, it denotes the fallen human race, corrupted and usurped by Satan to be the components of his evil world system. In 1 Pet. 3:3 it denotes adorning, ornaments. Here, as in John 15:19; 17:14 and James 4:4, it denotes an order, a set form, an orderly arrangement, hence, an ordered system (set up by Satan, the adversary of God), not the earth. God created man to live on the earth for the fulfillment of His purpose. But His enemy, Satan, in order to usurp the God-created man, formed an anti-God world system on this earth by systematizing men with religion, culture, education, industry, commerce, entertainment, etc., through men's fallen nature, in their lusts, pleasures, and pursuits, and even in their indulgence in necessities for their living, such as food, clothing, housing, and transportation (see note John 12:312). The whole of such a satanic system lies in the evil one (1 John 5:19). Not loving such a world is the ground for overcoming the evil one. Loving it just a little gives the evil one the ground to defeat and occupy us.
