For all that is in the world, the lust of the flesh, the lust of the eyes, and the pride of life, isn't the Father's, but is the world's.
is not of the Father, but is of the world: This "trinity of evil," which plagued Adam and Eve in the twilight of time (Genesis 3:6) and challenged Jesus shortly after His baptism (Matthew 4:1-11), has its roots in this evil system of things. It does not proceed from the Father in any form or fashion. The little word, "of" is ek, meaning "out of," expressing source. God is not the source of evil desires or vainglory; they spring from "the world." As Lenski says, "The Father is the source of light, life, blessing, holiness, salvation; the world is the source of sin, lust, ruin, death" (427).
