"To come into the world is used in the Talmud of certain persons (e.g. Abraham, Isaac, Jacob) or of men generally who come into the world, i.e. men; all who come into the world.
It is also used of events (punishment comes into the world) and of things: something which has not come into the world, i.e. which does not exist. Corresponding phrases for to go out of the world (to die) are to leave the world. In such phrases kosmos [world] is mostly used without emphasis to denote the theatre of human life. When it is said that man is born into the world, (eis ton kosmon) or that we bring nothing into the world (1Tim. 6:7), or when death is called a departing out of the world (ek tou kosmou), such expressions have no specific cosmological or theological content."
(Theological Dictionary of the New Testament article on "kosmos" Vol. 3, p. 889.)
In carrying out our study of Johannine theology, it is important to understand his use of the word "world," kosmos…..The earth is frequently referred to as the dwelling place of humanity in language that is paralleled in Jewish idiom: coming into the world (6:14; 9:39; 11:27; 18:37), being in the world (9:5a), departing out of the world (13:1; 16:28b)….the idiom itself is familiar Jewish terminology. To come into the world means merely to be born; to be in the world is to exist; and to depart from the world is to die.' There is no element of cosmological dualism or of world denial in John.
